I got caught looking at my friends answers during a test?

I know, you shouldn't cheat...but to be honest, it was only one question. And everyone has cheated before. I don't do it often, I just really wanted to do good on this test b/c progress reports are coming out. But anyways, my teacher saw me looking, & then he looked at her, looked back at me, and then smiled. He didn't say anything to me afterwards, and he was being nice to me and all. But I'm 100% positive he caught me. I dont think he gave me a zero, but I don't know...has this ever happened to you? We have a 2-week break now, so he might forget. Maybe? Ugh. I feel bad for cheating...
