Oh I forgot to mention that he frequently asks me to scratch his back or examine bumps on the back of his neck etc. So I guess he is not flexible enough to scratch his own back. If I ask him to squeeze my shoulders he does so begrudgingly so I stopped asking. Should I continue to scratch his back when he asks? It's not something I would do for a roommate. I like being asked but I'm not sure how it works within the 180 plan.
