How comfortable do most people feel here describing themselves in terms of their partner and children?
I think I would only do this when ringing my daughter's school, because the person on reception needs to know that it's a parent/carer/guardian making the call. Ditto at a GP's surgery.
I'd never ever do this in a social context i.e. I wouldn't announce 'I'm married to X. In more formal, professional situations if I was out with my Spouse I wouldn't object to being introduced as 'This is my partner/wife Marianne'.
But if I was out at a party meeting people, I just wouldn't think of bringing in my family life at an early stage in the conversation. I just don't see why it's terribly interesting, if you see what I mean.
