If you're wondering about something in the room I would just ask. My therapist has worked from home since the pandemic started seems like he's in an empty bedroom I know he lives in the house all alone. He has a tendency to leave his closet door open there's nothing in there but empty hangers and maybe a couple sheets at the top shelf but closets trigger me and I always ask him to close the door and he always thanks me and says sorry he forgot and he closes it. I've also asked or commented on the plant in his room that he took from the office or does he have an window air conditioner because I see a reflection in a picture behind him. last time I noticed he moved his printer that I can see now.

There's no sense in ruining your session by being distracted and something in the room might as well just ask.
