who am I
from: How I Met Your Mother
Robin : I totally wanted to come. I got stuck at work again. I feel like I live there.
Sorry, I missed your party again.
Ted: Hey, ain't no thing, but a chicken wing, mamacita.
Who am I?
Robin; I guess there's no chance your two-dayer turn into a three-dayer.
What does "Who am I?" mean?
I have no idea what I am doing?
or any other connotations?
