Mil is highly extroverted and loves talking to everyone. She lives in the US and visits us once a year for a month or so. She has met most of our friends and exchanged numbers with them. When she comes she makes it a point to get presents for all of them and to meet them. So far so good. I get along very well with Mil and have no issue with that. The only thing I don't like is that she insists on meeting them all (which can be awkward if we don't have time or for whatever reason don't want to) and she sometimes inadvertently tells them personal information about us. She is very helpful and generous herself but is also not above asking for little favours from them, which I'm not keen on either.
However, this time she's started accompanying me or dh to the school drop off and pick up. I'm quite friendly with quite a few of the parents there and have introduced her to them so now she chats with them as well. She said a couple of them have asked for her number now to stay in touch after she goes back to the US.
I know I can't tell anyone whom they can or can't talk to but am I BU in not really wanting her to have a separate relationship with them? These are ds' classmates' parents and we will have to spend years with them. Most probably it doesn't matter but it might make things just that little bit more complicated. I'm worried about crossed wires if she gives out personal information to them (there's no point asking her to keep things confidential. She just has a very different understanding of what is private) and I somehow also just won't want her to be good friends with them even if I'm not sure why. Maybe I am being super unreasonable?
