My T and I laugh a lot. We have similar sarcastic senses of humor, and it's easy for us to make each other giggle. Sometimes we have an all out joke/laugh fest
I'm like you - I go twice a week and we go to some dark and scary places. We used to sometimes have an intense session followed by a lighter session. But we seem to have come to a point where we can go to the dark places AND laugh in the same 50 minutes. I'm grateful for that.
