Look and I've got toddlers running around and a job that doesn't quit, so when my neighbors started borrowing tools and parking in my spot, I had to shut it down quick. Next time they asked, I said straight up, 'I'm sorry, but I can't lend things out anymore because stuff gets lost.' For the parking, I put a note on their car saying, 'This spot is mine, please park elsewhere.' It worked without much drama.
