My evidence is circumstantial

But I'm pretty sure my MIL purposely broke my side mirror in the shopping centre's parking today.

My mirror was fine when I got there. When I came out her car was in the parking behind me. And all of a sudden my mirror was broken. It had been pushed all the way out. There were no cars parked next to me when I got there and still no car next to me when I left (and I was in there less than 15 minutes).

There was no way someone could have hit it accidently because my car would have been scratched and there's no damage. And I parked away from the busy section to avoid damage as well.

I'd ask her of course, but she's the devil and she isn't even talking to my husband anymore.

I don't believe there are any cameras facing there but I plan on going to have a look anyway.

I am so angry.
