It's my birthday

We spend 364 days a year counting down to January 12th. 

On August 28th, I tried to find out what Evan did for my birthday.

At home:

B: What did you give me for my birthday?

E: I got your library book today.

After dinner:

E: This In and Out dinner! This is for your birthday.

B: I paid.

At the ward picnic: 
E: It's your birthday lunch! How do you like your birthday lunch?
B: This is a ward activity.
