What to answer to "cheers"? I recently meet someone near my doorstep (I just moved in, now living in a student accommodation). After a very quick presentation he said "cheers" and then carried on his way. Confused, I said cheers as well, because I didn't know what to answer. It is not the first time I come across this word however. "Cheers mate" is a common sentence to here in the street, when you do a little favor to someone (bring out a lighter, carrying luggage...). But here the context is different. I've done nothing to be congrat for, yet I got this "cheers" that confuses me.
