Well if it makes you feel better, My first time handling a snake, which was a ball python, i was 100% fearless for about 2 minutes until it yawned.... then i put it down on my lap and it sat on my lap for the next 20 minutes until it crawled off. I was not touching it after that.
In my defense, I had no idea why it opened its mouth and wtf it was thinking, didn't know jack about snakes back then. but looking back, yea it was just yawning.
in my experience with all my ball pythons, they ball up as babies when their afraid, not bite like other snakes. which for us keepers makes them conviently easy to pick up. really just pick em up, its a ball python and it most likly going to duck and move really fast to hide its head, not too many ball pythons bite. its gotta get used to you, just like i guess you need to get used to it lol.
