This is more of a who's right than AIBU, but I'm going to come straight out and say who's who.
Going on holiday next week, and booked a cat sitter to come and feed the cat. We actually messaged a few different ones and struggled to find availability - our usual one was booked up. Anyway found this lady who used to help us out, she said yes, no problem.
She came to do a visit to sort arrangements etc and brought a couple with her, they are going to help her do the cat visits. They said they might not be able to do two per day (which is what we wanted), so I said oh ok it may not work out then - to which DH said it's ok we can make it work, i.e. With friends/parents helping out. I thought if we could do that we wouldn't need a cat sitter in the first place but I let it go.
So fast forward DH goes to drop keys off and gets chatting, this guy says that the original lady who helped us no longer lives in the area. I said (to DH later when he's telling me) well why not just say no then, but apparently she wanted to help us, despite not having seen us in years (and only then for cat sitting, we didn't know each other). So the couple are going to be doing all the visits as they live closer. They agreed to do it as a favour to original lady (their friend) but have now told DH they're happy to do it for free! We have never met these people. Obviously we won't be allowing that and will be paying them for the visits they do.
DH feels they are just nice people, I agree with that and they seem lovely but I was brought up with "if it seems to good to be true it probably is" and to be more wary? I just don't know why someone would do that or behave like that. Is it me and I'm too paranoid or is DH too trusting?!
If they are genuinely this lovely then great, and it's nothing about them personally, as they do seem nice. I just feel like it's a bit strange... And I have handed my house key over to them.
