I've heard retics will give a number of indicators that they are not into you before they bite. At least in general.
My boa is great, but boas are very different and don't let on as well IMO when they are going to snap.
They are very stealthy and of all of my snakes, I'm still most cautious with the BC.
My carpet on the other hand is like a person. "Oh HI,,,,, shall I come out and have a spin around?"
She's great and I have done things that should cause her to bite and she just won't.
My new retic and I are still learning each other.
