This has never happened to me before but has now happened twice in a fairly short span of time and both times at the same car park.
So both times I've got back to the car and there's been a space free next to me on one side. I've gotten baby DS into his seat then moved DD's pushchair round to the other side (I have her where I can see her while putting DS in) and opened the door so I can put her in. I probably opened the door wider than I would have if there had been a car next to me. Anyway, twice now some guy has decided that he needs that space right that second, one time this man sat there beeping his horn and gesticulating and today someone just decided he was going to back into the space anyway!! He must have ended up parked so close to the car on the other side that I've no idea how he got out.
AIBU to think that if someone's getting their kid into the car then the normal thing to do is to wait for them to finish and shut the door before you try and park? I'm not faffing around getting DD in, I've got shopping in the back and two kids - I don't want to be spending a second longer sat there than I have to! Even weirder, both times there were alternative spaces not far away.
