I can't say this day is somehow special for me. I invite my friend because I'm often her guest. I visit my aunt because she's my family. As far as having fun goes, I don't think I need a special day for it. For example, I have a holiday in the mid May, when other people are working and stupid children are at school. I'm going to the seaside and there is nothing worse than a crowded beach with little screaming fuckers running around and parents yelling at them.
So narcissism.
But I tend to revel over the joys of vital existence regularly throught the year. Or maybe I'm an alcoholic and a manic adrenalin junkie,,,,, there is that possibility.
