I've heard my T curse in group therapy, basically just restating what someone else said. It took be back a bit....

When I found my anger towards my parents (which I have since suppressed and need to find again), I found myself saying the F word once and the sh word a couple times....And it didn't phase him.

I also restated something my sister said to me that used the ******...and he repeated it.

So, I'm assuming my T is ok with cursing....but I don't like to make a habit of it.
