You dodged a bullet. tbh I thought this was going to drag out and get uglier.

When I was a kid our parents let some family store all their stuff in our garage (for free) "for two weeks" until they got a new place. Six months later we were putting it out on the curb and they were cursing at us and threatening us.

I was probably 8 years old but learned a lesson for a lifetime. Screwups are always looking for some sucker to sign up to be their next victim. Don't sign!
