Does tired look mean that I've been drinking heavily....

Turkish ERASMUS student: Do you like to drink?

Me: Well, how to say... I drink... but not very often.

Turkish ERASMUS student: So you don't like to drink?

Me: Err... No, I like... just I don't drink every weekend... or every day

Turkish ERASMUS student: You look tired

Me: Yeah I know... but that's not because of drinking...

:D
