When Alice was about to come home because of the curfew, I sent Kev off to visit a random house in the neighborhood, to keep him out of the way. When I next went to check on him, he was in the bath of a house belonging to a couple of old ladies.
It seems that due to his inappropriate trait, Kev will choose under his free will to do the kind of things that get Alice thrown out of a house. But he seems to get away with it. The little old ladies did eventually ask Kev to leave, when it got too late. He chose to kick their bin over in protest.
Instead of going home, he spent the night in their garden, then immediately went to ring the bell again in the morning.
With his lifetime wish for romantic partners in mind, and his previous experiences with women disliking his choice of conversation topics, this time he went straight for a kiss.
Dejected and shamed, he went to sleep in her bed.
