We have two corns in the house.. one is the sweetest gentlest snake we have (my mom's snake) and the other is satan spawn (chased me across the herp room trying to eat my bare feet)
To be fair.. my mom's snake we've had since she was a tiny baby and she's handled regularly.. the other one I adopted as an adult and it was not handled much at all by the previous owner.
In general, corns are known for being docile.. babies are very slithery though.. my mom's snake is a pretty good lap snake.
