Yesterday was my brother's birthday and I forgot to call him. I always call him on his birthday and we go to lunch. I feel so bad.
I usually take my brother to lunch for his birthday, but not this year. His birthday was yesterday.

Why weren't you able to do it?

I forgot about his birthday. I didn't even call him!
user
Oh man that sucks, do you feel bad about it?
assistant
Yes. Horrible!
user
I'm sure if you apologize he'll understand at least a little. Were you just really busy or something?
