Stupide!!!

How can I forget about her birthday?!
What a dumb ass I am!
She must have been anticipating my presents when she found out I was back.
Though she seemed like she was totally ignorant about her birthday, I know she still care about it.
How disappointed she might feel after she knew I really forgot about it!

Oh god, how can I be such a careless selfish brother!

Wish I can find a way to compensate her.
Dame!!!
