Once my kids move out of the house I'm living in, I can't say I have that much interest in them. If their mom wants them 100% of the time, I'm OK with that, I always avoid all and any confrontations. I refuse social phone conversations with everyone, no interest on talking on the phone.
My Thai step-daughter moved out a year or two back, after finishing her degree, I don't talk to her either, although she's come back to stay for a weekend a couple of times.
I guess that makes me a bad man.
