SIL and I share a cleaner. The cleaner has been coming to me for about 18 months and I recommended her to SIL shortly after. I've never discussed SIL with the cleaner.
We have completely different relationships with the cleaner: SIL has been chummy with her while I work fulltime so barely ever see her. My DH and DC do, and they like her.
The cleaner is quite flakey (says she'll come on a Monday and you don't see her til Wednesday, etc) but this is fine by us because we really just need the hours of work done - doesn't make a huge difference when. She has a key to the house and I trust her.
For whatever reason, the cleaner's just decided not to go back to SIL. The cleaner didn't tell SIL, she just gradually stopped going round. She still comes to us though. SIL thinks the cleaner stole from her. SIL is totally bemused as to why cleaner stopped coming.
SIL wants to get her key back from the cleaner and to 'get closure'. She wants DH to tip her off the next time cleaner comes to us so SIL can come over and get her key back and speak to cleaner. We absolutely do not want to do this. Cleaner seems honest and we don't want her to come to us and worry she'll have to see SIL.
DH said No, we don't want to get involved. SIL gone bonkers and said we aren't supporting her and we are involved as we recommended the cleaner. Who is BU?
