Dp is taking part in a sporting thing today - not a straightforward competition, more a big celebration, and it's a chance for the club members to do their sport somewhere pretty impressive. Fun day, once in a lifetime thing. Don't want to out this by more details. He's really excited about it. Friends and family can come to watch. Of course, I'm going.
So were his parents. Till 6pm last night when they rang and said they can't as one of them is going to do their own sport today as they are partnering someone and 'can't let them down'. They've known about DPs thing for months. What about letting him down? You might think ok, doing a sport trumps watching a sport, but they never ever come to watch him and this is a big deal, whereas theirs is pensioners doing what they do 2 or 3 times a week in a not-serious way more as a social hobby. They are a bit strange - they will go and spend a couple of hours doing their hobby while they've got visitors, for example.
The one not doing their sport today (they've only got one car between them) was actually offered a lift to DPs event but turned it down as they find the person boring. Or, you know, there are trains up to us and then we could have taken them. Or perhaps the sport player could have got a lift from their sport partner, leaving the other one the car to drive to DPs thing. Or perhaps they could have told the person wanting to play with them that they already had plans for today...
Poor DP. He's putting on a brave face but I know he's hurt.
AIBU to say something about it to them, or should I just leave it.
