Jeepers creepers...

We just got back from the park. There was a guy there that was just straight up creepy. Seriously as soon as we pulled up I saw him and my freak-o-meter went off. I let my kids out to play and told them not to talk to the guy. He had a camera and was taking a picture of some girl (she was about 18-19 years old). I never took my eyes off him. He finished taking the girls picture and she left. So he starts walking toward my daughter and I was like hell no your not going to talk to her, so I started to get up to go over to where she was, but he got there first and said something to her.  She came running over and said he wanted to take her picture. He was watching me the whole time she was asking. I told her no he couldn't and that a grown man doesn't need to take her picture.He saw me telling her no.  So I sent her the other direction to play and stressed to not talk to him. Then he walks up and asks me if I have an email address. I said yeah. He said he could take pictures of both my daughters (my son apparently wasn't his thing) and email them to me. I glared at him and pretty much told him off. He got uncomfortable (could have been the I hope you burn in hell look I gave him)  and  tried to make small talk for a second and then went and sat in his car and I stood there and watched him. I must have made him nervous, because then he left. I was thinking though that I should have got his license plate number because he had a big van with tinted windows and out of state plates and the whole thing was just really freaking creepy. The guy was a slime ball too, really homely and dirty and he was using crutches, except that he wasn't really using them at all.I didn't think about the plates  until he was already leaving and I couldn't read them.
