God Bless the Language Barrier

Every Friday the office admin brings in breakfast for the whole floor. Today it was Lao sandwich (kind of like banh-mi, the Vietnamese baguette).

Here's how the conversation with my Lao coworker went-
Coworker: "Katie, you don't eat sandwich?"
Me: "Oh, no, I will, but I just had breakfast at home so I'm kind of full." (holding my stomach, gesturing fullness)
Coworker: "Oh, so you go on diet?"
Me: "Oh... uh. No. I just had a lot to eat so I will wait for sandwich."
Coworker looks at my stomach and nods understandingly.

I still think he thinks I'm on a diet.
