T encourages me to email because I have a hard time speaking, and he always responds. I only do it about once a month though.
I sometimes text in crisis...maybe every couple of months or so and he usually has me come in for extra session. Those after text calls are odd

T: What's going on wiki?
Me: um. ah. kind of hard.
T: ok, do you want to come in and try to talk?
Me: sure. is that ok?
T: Yes, I would love to see you.
