Social distancing is a significant enough obstacle as it is without some sports deliberately social distancing themselves from their own members. Tennis has long been a sport where inequalities of all types have seethed.
Irish tennis No 1 Simon Carr has just had his latest lockdown dinner with the family in Mullingar, including dad Tom, former Dublin player and manager.
All of which may or not be news to Austrian tennis No 1 Dominic Thiem, who had not seemed to recently care whether his fellow professionals had managed to consume their daily bread.
The last time we checked, Thiem had amassed a not inconsiderable $23,873,943 (€22,095,334) from a career which may not even be half completed.

Carr, the last time we checked, had pocketed the grand sum of $6,757 (€6,253) this year - less considerable expenses - none of it involving a shared ride on Thiem's private jet.
"No tennis player is fighting to survive, even those who are much lower-ranked. None of them are going to starve," scoffed Thiem, as tennis attempts, slowly, to redistribute some of its largesse to the least well-off.
"I don't really see why I should give such players money."
In a sport where the top-ranked player and head of its playing association has declared he is anti-vaccine, perhaps such delusions of grandeur are to be expected.
Carr trains for hours on end every day, in his converted garage along the banks of the Royal Canal, and along the greenway cycle path; from next week, mercifully, on the re-opened courts in Mullingar Tennis Club. But for what?
He knows not when competition may resume for him; the French Open insisted yesterday their delayed show will go on.
But, for those bubbling beneath the exalted air breathed by Thiem and company, life may remain on hold for some time yet. The proposed players' fund, which would effectively siphon off funds worth approximately €10k per player for those ranked between 200 and 700 might provide some succour.
"Nothing has been set in stone about the player fund," says 20-year-old Carr. "There have been a few emails from Novak Djokovic. Talks are ongoing. I'd be pretty optimistic we'll be hearing from the ATP soon enough.
"I'm not eligible for the Covid-19 payments. I haven't been able to earn anything from the last two months. I've no expenses. And I'm happy to be living at home. But at this stage I just want to play.
"Dominic is entitled to do what he wants with his money. He's earned it but he was wrong to say a lot of the players aren't professional.
"Okay, a few tread water but the majority of them from 200 to 700 do work their a***s off and are away from their families 35 weeks a year."
He was in South Africa when his sport was halted; his tournament had already been halted with first round defeats in both singles and doubles, completing a difficult run of first-round exits.
Paying for his own flights and accommodation made it an expensive month, too. After competing in the sweltering heat of Cancun, then Dubai and Johannesburg, he has confronted a minor epiphany since lockdown struck.
"I needed to become a better athlete," he concedes. "I needed to get more speed into my arms and my legs. There are so many things to work on. And none of us will ever get this chance again.
"Our lives have frozen for the last eight weeks now and it is a perfect time for a re-set.
"But it's monotonous having the same routine without matches. I was really de-motivated today.
"But I'm lucky. Some people I know have been in an apartment for two months. I've got green fields around me."
Tom puts him through his paces; sister Elizabeth, a triathlete, ensures there is plenty of sibling rivalry too while the resumption of golf and tennis next week will provide some competitive release.
"Even if it is just for a fiver, having a chance to get the competitive juices flowing again will be so important. It's been great having dad helping me as my physical trainer. He knows what it takes to get a team in shape."
He has all the support he needs but would like more; notwithstanding their limited resources, he is disappointed that the governing body, Tennis Ireland, have failed to support him during his nascent career.
"Tennis is an extremely expensive sport," says Carr, who is fortunate to have a few private sponsors to help him survive on the gruelling, unglamorous Challenge Tour circuit, very much off Broadway.
"Costs can add up pretty quickly when you have to pay for everything yourself. I've been told for quite a while that Tennis Ireland would put financial support in place but nothing has happened.
"I have no idea why and there are a few others also. Being the No 1 and having a decent ranking, I would have hoped I would qualify for some funding.
"I have colleagues in the UK who have coaches and nutritionists with them whereas I travel on my own. You don't want to sound like you're complaining but it's just the reality."
