My 13 year old boy is obsessed with my sister... The funny thing is that she doesn't even live with us (we are both grown and have our own homes). She comes around on the weekends and he won't leave her side. She even takes him once in a while for a sleepover at her house. Funny though how I'm the one that walks him and feeds him and baths him...he does like coming home at least and gets very excited to see me but still not the same level of excitement he gives her! I joke that they are soul mates
