Our BP frequently does not want to go back in and attempts to hold on to us or quickly climb up and escape before we close her tank. It's normal; he just wants to hang out a little more.

Also, the calm behavior when out could be b/c he was cool when you took him out, he just feels calm, etc. Could be a million reasons that are normal. Our snakes have their moods and also react to who is holding them. They tend to "snuggle" with me and go for a "run" with my husband and kids.

Just keep your eye on his behavior to make sure he is OK. If you start to worry, take him to a vet. But IMHO, it sounds normal.
