You're not sure yet that he lives in the neighborhood tho right? People don't do this stuff Lynn. You've never ever met. Can you perhaps ask your other neighbors about him? Just plain out say what you've said here. This guy is repeatedly coming to our house etc etc...washing hands etc. Who is he Etc. If there's no satisfactory answer from them I'd contact the police. Our neighborhoods are not so diff. in Canada and the US. That amounts to repeated trespass. Most people are willing to give the benefit of the doubt once maybe. But repeated stuff like that with no introductions or explanations doesn't fly here and I'm sure it doesn't there. Life is too weird not to be cautious.
