I think a t could possibly not respond right away if the client has issues with not being able to tolerate boundaries, in order for them to learn they can't always expect instant gratification. But it's not to be mean. It's to teach the client that they can tolerate the discomfort of waiting and use their coping skills. Also teaches them that even if they have to wait, t will respond when she can. They can be trusted to be there for you, but not always immediately. T's try to teach us llife skills. Like in real life, we can't always expect somebody to respond to our requests immediately. However, in an emergency, I think it is the t's responsibillity to respond promptly. That's different.
