My ball python, Tiny, who I adopted this past summer is the sweetest and gentlest snake in the world and I love her dearly. I am just a tad bit confused, she wrapped around my boyfriend's hand and started squeezing rather hard. He had been handling her for the past few minutes and then I left the room to take a shower and apparently while I was gone she started to constrict his hand. My boyfriend is not angry or anything, he calmly unwrapped her and put her back into her enclosure.

Is this normal behavior? He was handling her with no problems at all and this is not the first time she has spent time with him. Maybe it was just a misunderstanding?
