I celebrate birthday with friends. We go to a bar and drink a lot. Hahah
With family and friends.(Not same time)
In Japan, the person who have a birthday don't organize the party. Other people organize for the person.(Often it's surprise)
So, I will be with my family and friends because they organize for me^^
Usually alone, because i don't prefer to celebrate "My" birthday, and the date of my birthday is summer vacation season, so we can not meet up at that time.
一般和家人或者朋友一起庆祝一下,人多比较热闹。
Normally, I celebrated with my boyfriend
I will celebrate with my friends. We will go out for dinner or go to the theme park
with friends and family
Children want to get along with their friends with some food
