I don’t understand what’s wrong with that woman. If she doesn’t like her cat enough to allocate resources to poster-making, why does she try to act like she cares about it? She spends more time asking someone to do something than to do that thing herself. No wonder the cat ran away.
Be careful about judging. Some people really don’t have good coping skills at all, so when something happens they don’t see things clearly. She probably doesn’t realize that she didn’t go about that the right way, and didn’t understand why someone would respond as they did. At the same time, it’s easy enough to explain to someone why they don’t do free work, or that they are too busy, whatever. Sure, it’s funny, but there’s no excuse to be an asshole to someone, especially straight off the bat.
