I've got a snow corn too! Her name is Aurora, and she does just the same thing as yours. Cool, calm, and collected at all times. Loves to just relax and squirm here and there in between my fingers, on my hands, etc. Just watch out! The little sneaks will wait til you're nice and calm and not paying attention, then... hey, let's wrap up in her hair really good! It hasn't been brushed yet today, OOO this is fun! What's this? A crevice in the seat cushion? That looks fun too!!! Corns are awesome, awesome awesome awesome! But with anything, it depends on the snake. Once in a while you may meet a mean or flighty one, but in my experience they're all beautifully tempered. (Used to work at a pet store... it was a joy to work with the corns!)
By the way, that's a BEAUTIFUL snow corn you have
