Happy birthday xD
I see the importance of birthdays, not just to show you've 'survived' another year, though the thought does cross, i believe, everyone's minds. I see it as that one day in that 365(.25) that is 'your's', a day to reflect on your past, what you've done since your conscious existence and what you try to do for the future. In another sense, along with it being 'your' day, a birthday is like the myspace/facebook/bebo/... of life, to edit and do with it as you see fit.
Despite this i don't celebrate my birthday lol. Mostly not having anything to look back on or forward too. Plus i have most of the possessions that I could get with my parent's budget. regardless any gift is a great gift to me. I tend to spend that 21st of may (

) In my room like any other day, gaming, preferably with a significant other.
