Creeper guy ruins potential first kiss moment. Erg.

So I've been on a few dates with this girl, I haven't kissed her yet, we've just been holding hands. There had been a couple of moments when it sort of seemed like it could be a good moment to kiss her but I kept chickening out. Then towards the end of our date we had sat down for a little while. A guy walked by and said hi to us. I had been glancing around checking to make sure there wasn't anyone staring at us or something, because I reaallly wanted to kiss her.. but not with a bunch of people everywhere. And then I realized the guy had sat down and was staring riiighttt at us.. grinning. And I never got a chance to kiss her after that.. =/
