So there's this girl i like, we have a bunch of classes together. I'm sitting with her one day, and her and her friend seem to be making plans to go somewhere, I've got somewhere to be, so I say good bye and go for a quick lunch. I end up running into her in the cafeteria and she jokingly comments "What are you stalking me?" I laugh, we move on with conversation. At that point, I decided (also some advice from here) that it wouldn't be a good idea to 'run into' her too many more times, just in case she's at all creeped out. Well, yesterday I was with a couple friends and I saw her in the hallway, and she saw me, and I wasn't even trying to run into her! I was going to go and talk to her, but she walked off somewhere else before i could get her attention. If she is actually worried about me being creepy (even though I'm not) what can I say to her that will relax her about it? But not sound too weird if she doesn't feel that way? Should i just pretend like it didn't happen?
