If he can group things together like his 'toiletry kit', then I'll do the same with my clothes (though I have toiletries, too). Aside from my clothes, I have 10 books, a laptop and a cell phone. If we're going off of things I'd be pissed if someone stole then that'd be my MBA and all of my clothes...so I guess I kind of own two things.
I've lived like this for 10 years.
