However on your birthday you always eat what you want eat, sometimes you have cake (In my case, I love the ice cake of raspberry and cream...mmmm) and the tradition of blowing the candles and make a wish it's so pretty.
I don't know if you know but many places give you a discount for your birthday, so you can get out to eat something and its cheaper even you can go to watch a movie for free! I always dream of making a lot of different things like that in my day but for some reason my birthday falls on a weekday and I have to go to classes or do another more important thing than going for a wile to the movie.
A good side is also that nothing is close! Don't you hate that when it's Christmas all the supermarket, all the restaurants, all the service in general are close! I understand the reason but, to prevent not to lack of anything you have to go shopping an entire day even days before! All the shops, the streets, everywhere you look is full of people and it's exhausting
So yeah, I think my favorite festivity is my birthday even though it could be New Year's too.
