Really? I always thought it was the other way around due to disappointment and the realisation of loneliness.
Oh Mark, that sounds so sad
You don't need Valentines Day for disappointment and realisation of loneliness, that happens to someone every single day. Not everyone is loved and cared for but to me Valentines Day is a celebration of happiness and love and whilst I have both I'm damned sure I'm going to enjoy it. It does make people happy, not everyone, but then nothing does.
