Unlike everyone else in here, I want to give him the benefit of the doubt.
Things like the smell and china are sensory issues, I think those ones at least are completely worth respecting. I have had many a meltdown from people using scents near me, and it is miserable when that is in your own home.
Sometimes when I am very over stressed I have a very hard time lashing out against people. But realizing it isn't their fault when I know I am like this I will go to my own room or a place people wont bug me, and actively avoid them as to avoid lashing out.
If he is like this, but not going to a private place, then he is just being a jerk, if he doesn't have one to go to, well that is something to talk about. But through email or writing.
