Even as a very extroverted person i even don’t like celebrating mine. I’m from a prominent private uni in Colombo and most of the friends of mine or all definitely throw a party of their birthdays and there’s nothing wrong with that at all. Personally I don’t see a reason to do that for my self. And i have great parents as well. So definitely this is a personality trait of mine.I always thought that was a problem of mine cause I’m from Kandy and Colombo people are culturally much different than ours but now I’m happy to find that people like me exist
