My 3 girls all have slightly different personalities. Chiquita, my Banana Yellow Belly was the most flinchy/jumpy but she has noticeably mellowed out very quickly. She still flinches a bit, but you can feel her relax now.
Daenerys, my BEL, is the sweetest. When she is out she will explore only as far as she can without letting go of my hand. She will stretch out and look around, keeping her tail wrapped around my fingers, even when my hand is on the couch, and she always returns back and rests her head on my thumb to just chill.
The other night when putting her back in her tub, she stretched over to her water dish, flicked her tongue at it a couple times and then stopped to take a good 30-40second drink before working her way down and towards her hide. It was so cool watching her take little gulps of water and she only let go of my hand once the first third of her body was inside of her hide.
My point, they are all a little different. Sounds like you got yourself a good one.
