Is it a good sign if a woman keeps looking at me when she laughs?

I was at a housewarming party last night and a lady I know also came. I wasn't expecting her there (I wasn't even expecting a gathering), but she and 3 other people showed up. The only reason I was there was because I'd gotten my friend a house warming gift and he told me what time to show up.

This woman and I have always had a decent relationship, but distant. She's always sort of held me at arm's length. Tonight was pretty much the same. The conversation between us doesn't really flow. I've kind of gotten the vibe that she generally has a good vibe about me, she's just not really comfortable opening up to me one on one.

After other people arrived the conversation started to flow. I noticed she was often looking over at me when she would start to laugh. Someone would say something funny, she'd look over at me, then she'd laugh.

Now, I'm not an idiot (that's not true, I am DEFINITELY an idiot), so I'm not asking whether this means she wants to have my babies or some shit, but I wondered if the fact she was looking over at me is a good sign?
