My T always picks up on the things with have the same, take last session, we were sorting out my next session and we both had our pens out, when she goes

Oh, look we have the same pen, and starts chuckling to herself about it.

Then one session she forgot a clock so we used my phone to keep an eye on the time, and again she goes, oh we have the same phone, and starts chuckling to herself.

Does your T do this is, I just find it strange that she mentions it.
