Sarcasm much?

My father uses sarcasm on a regular basis. It's just built into his personality or something. I'm pretty sure that he's more sarcastic then I ever was as a teenager.

Me (seeing Papi grilling): "What'cha doing?"

Papi: "What does it look like I'm doing? Greeting aliens on another planet?"

See....I was just asking a simple question. Of course I knew what Papi was doing: this was a conversation opener, a chance for Papi to tell me about his life and not be a weirdo. But did he?
No.
