Well I talk to myself too, especially at work

On the train, and suddenly a lady beside talked to me.

Lady: "You got a pen?"
Me: "Huh?" (Didn't realize some stranger on the train would talk to me with a hey buddy tone)
Lady: "You got a pen?"
Me: "Ummm... no."
(Tried to find comb in bag, she tbought I was looking for a pen)
Lady: "Got a pen?"
Me: (Kind of found one) "Yea."

And she was talking to herself (or me, not sure) and she alighted at Tampines.

Note to self: talking to myself might look really weird to others. It's ok to be myself but don't make people uncomfortable.
