he is a fictional character...................
*worst
OT: Yeah it's been pretty crappy. His friend Neji got killed on his birthday and there's the whole world domination thing going on. But he also got to see his dad personally and his best friend is fighting by his side at the moment so it's not all bad. Naruto has spent the majority of his birthdays absolutely alone so he really might have had some worse birthdays growing up.
He is having the time of his life, he got those super strong powers from Hagoromo, that makes up for something.
