Celebrating one's own birthday is a bit odd if you pause a moment to consider it. After all, you did very little that deserves celebration on your own birthday. You basically just showed up and let other people do all the work. Celebrating this event is pretty self-serving. In an ideal world, the birthday celebrants would be the mothers who gave birth. They'd give a toast to not being able to drink wine for 9 months (x) amount of years ago, and then they'd get free drinks all night at the bar. Sadly, this is not the case. Ultimately it's just another example of how giving mothers can be.
