Do you ever feel the need to process positive or neutral things with your T?

I know T has told me he wants me to be able to talk with him about anything so I assume positives fall under that heading of anything. Sometimes the need is stronger than others but it is always there at some level to process our first session together. The session was a much better, more comfortable experience than what I expected it to be. The phone call was aweful and there was a ton of anxiety. Going to the first appointment, sitting in the waiting area and the first session itself were really peaceful (?) and I feel like I need to process this with T. I mentioned it to him in an email and he has not brought it up but it is normal for him to not bring up something sent to his email.

So I am interested in others experiences of processing positives or if you ever went back and processed the first session.
