You didnt know. When you did, you responded and respected his limited availability. Thats what was important. I just encourage people to take this as an example. T's also have difficulties, lives, random crazy things. So when they cant respond quickly it may be because they too have stuff that is outside the therapy room. Its okay to need T, really. But I hope it also encourages clients to pause when T may be off their game a bit. You responded exactly as you should have.
