Hi I am an ESL student and currently travel to USA to learn some English and the culture. I know sometimes there are hidden meanings in the everyday slangs and recently a male teacher asked me to "have a drink some time with him." I don't know if it's really have a drink or there's more, you know, romantic hints or something. And forgive me that I don't quite understand the western culture here.
Anybody could help me out to decode this please? Thanks.
