I have some empathy for the OP, no harm in asking, and the "parkee" could have been more forthcoming as to why he needed to remain in the space. I would have probably moved but I don't have any kids to pick-up, maybe diapers to change, or other extenuating circumstances creating a need to remain parked. The "parkee" could have been more sympathetic to the OP's plight in explaining his overriding needs to remain parked.
The thing is this, he was under no obligation whatsoever to give up his space.
If she asks and he still doesn't want to give it up, he is not under any obligation.
The problem her is that people tend to evaluate the own circumstances as more urgent than the circumstances of others, in this case Cindy assumes the guy is being rude but she doesn't know anything about him, for her he was being an a-hole because as she saw it, she was in greater need than him, otoh, he could be chatting on WhatsApp with other parents and telling the story about a self absorbed person that demanded him to leave his car regardless of the wellbeing of his two children.
My point is that is too easy to judge other people as bad because we don't know what happens to them and we don't care, we just care to make them look bad because they didn't do a favor for us.
There're various kinds of biases in this case, is not OP's fault, we all have them, the problem presents itself when she doesn't recognize them and keeps paddling in the wrong direction.
