I've learned to be more careful about letting Riddle hang out in my clothes, almost lost him that way 2 weeks after I got him :O
I was holding him and he fell asleep in my sleeve... I thought I would be able to feel him, nope, next moment he was gone! I searched for an hour before I had to go to the bathroom, next thing I know, I'm on the toilet and he comes slithering out of my pants onto the floor xD
Any how, not mine, but my friend's snake likes to crawl up people's head's and just rest her head on the top.
She'll get comfy in pretty much any position and will just stay there. One time I was messing with my boyfriend and I pretended to hand cuff him with the snake, well, she got comfy and made him stay like that for a really long time, when he tried to get her off, she held on tighter xD
