DP and I both work but due to insecure jobs / wanting career development have been looking for new jobs for over a year. I have told his parents several times (when they've asked) how stressful and unsettling it's been, and how hard we are job hunting. Recently, DP got a promotion at work - I was absolutely over the moon, brought home champagne, friends phoned to congratulate, my parents emailed etc. etc. I suggested he should let his parents (who live overseas) know so he skyped them and their response really made me wish we hadn't bothered! I was not part of the conversation however could overhear and am wondering if I'm being unreasonable to think they were out of order.
They did not say congratulations or similar, and instead quizzed him on whether it was really a promotion, whether his employer was taking him for a ride, whether it would fall through etc. etc. They have no reason to think any of these things would be the case. In the same conversation he told them that before this promotion he had an interview in Scotland, and rather than sympathising that he didn't get it they were very rude about Scotland, the possibility of moving somewhere colder etc. etc. and actually laughed at him, or at least that was the impression he was left with.
My only explanation is that they really do not understand the sector we work in, or what work in the UK is like (they're somewhere where it's who you know and promises of opportunities can fall through because nothing's done by the book). However I think it was really mean of them to respond in this way. It completely brought the mood down as he was left feeling they were unsupportive and didn't think it was anything to celebrate, and I was left feeling extremely annoyed at them!
Am I being unreasonable to think this was really mean, rude and disrespectful of them? Or is there another explanation? Any suggestions for appropriate way to respond in future incidents of this kind?
