Katie Byrne: At Christmas, it's the little things that send you over the edge, from the wonky tree to the in-laws
The world is divided into two types of people: those who giddily tune into Christmas FM on November 28 of each year; and those who lose the will to live when they hear Mariah Carey explaining that she doesn't want a lot for Christmas for the third time that day.
The latter group are often stereotyped as joyless, parsimonious 'bah humbugs', but UK-based clinical psychologist Linda Blair is of an entirely different opinion. She reckons they're just being mindful of their mental health.
Speaking to Sky News last week, Blair explained that shops playing Christmas songs repeatedly "might make us feel that we're trapped".
