Someone showed up

Knock me over with a feather! Nice guy from the construction place we contracted with. He repaired stucco and also repaired our fascia. He told me that nails aren't going to stay too long cause the people that built the house had used paper of some sort but that it wasn't a big deal as long as we kept it painted. I told him we weren't planing on putting up shutters or anything that would require nails. Not sure what to think about that. Another thing that bothered me was he was eyeing our new riding mower. He made a point to ask about it. Kinda creeped me out and made me uneasy. Then some people pulled up to the house and supposedly said something about someone falling off a scooter or something. I don't know it was suspicious and here our garage is wide open for all the world to see everything that is in there. Maybe I am being paranoid?
