most likely he is your neighbor but a little... strange, pushy, etc. can you descibe him to me? age, style of dress, stuff like that......
i only asked because if it was a teenager, old man or someone your age i might get a different impression of the situation, ya know? hm i dont really know but with men... ive run into people like that and usually they just want to get into your pants and are desperate for that. i guess just relie on your instincts- i mean, maybe this person just really wants a friend but you never know... you have to be a bit paranoid and careful with people.
