They don't love being handled per se, they love being free. My Boa liked to set on top of my computer monitor when he was young enough to fit, and then behind my laptop when he outgrew that. Now he likes to chill on our 56" plasma tv. It's all about where the warmest spot around me is. He'll find it and set there for as long as I'll let him.
He's alway preferred to chill out over roaming around. When it comes time to put him up though, it takes me ten minutes to get him in there. They are crafty about holding onto things so you can't get the doors shut before they are back out.
