He’s perfect, but…
Whenever the two of you spend a night in, he insists on wearing absolutely nothing except, inexplicably, a t-shirt.
Seriously, think about how absurd that looks. Just walking around the house with everything hanging out, yet, for some reason, shoulders modestly covered.
Oh, and he keeps all the lights on and blinds open in the evenings, so that passersby may get a bizarre eyeful as well.
Could you still find him un-ridiculous enough to be attracted to?
