I have a few that's the same, but variations of it. People who claim they want to do something, post once and disappear. People who claim they want to do something, post a few times and then make up excuse after excuse as to why they're not posting before disappearing entirely. People who claim they want to do something, but clearly didn't fucking bother reading an interest check. The worst is when they have the gall to give you attitude about anything later, had one of those not too long ago. 

The babies that need to be coddled or they're just gonna disappear or stop posting. I've no interest in talking someone into posting. That's silly, and shouldn't be necessary if the person is an adult.
