PIL have a key to our house, it was left with them when they babysat the DCs about a year ago.
Trouble is they decided it was a good idea to hang on to it in case they needed it again, to drop the DCs off or in case we lose ours.
Initially I was fine with that and agreed, but now they just turn up to our house unannounced and let themselves in, no knocking or anything.
To make it worse, DMIL also likes to just look through the window first before she even gets to the front door. It's really driving me bonkers.
AIBU to be so bothered by this? It just seems so rude. DP had a key to their house but it was his home for 25 years so I guess letting himself in isn't quite the same, they have never lived in my house but think it's fine to just unlock the door and come in.
DP had taken ds1 out for a walk one day and I was BF ds2 and trying to get him to sleep upstairs in our bedroom, and DMIL just turned up and waltzed in the door, then came upstairs!!! I find it so bizarre that they think this is fine but I really don't know how to bring it up, or get the key back.
