My brother left his car at the garage al day and overnight as it needed fixing. He gave the garage the entire bunch of keys which included the house keys and his car keys. I am having slightly irrational thoughts now. I would never leave my house keys with anyone. Is it crazy to think a member of staff might make a copy overnight and then rob the house at some point. Probably me being post baby paranoid but am a bit concerned now. Aibu?!
