I can't with my dad being old.

I can't with my dad being old. Like it's intermittent, too, so that makes it harder. It's monumentally unfair, of course, and judgmental, but when he turns into That Old Person it really bothers me. Partly because it's genuinely annoying, but partly because I can't deal. I mean, oddly, his subconscious seems to be aware of but not operationally interventional, so I think there's a sub-current of him not liking it, either. Like, being unable to do something you used to be able to do and getting frustrated. But, yeah, still basically my problem.
