I don't talk to my snakes often but I laugh at them all the time - usually when one one almost gets me. It's not a taunting thing either. There's just something about a snake zooming towards me, trying to eat the hand that feeds it, that gives me a good old belly laugh.
+1. I never talk to them, but laugh at them quite often when they do zany stuff like steal their neighbors dinner, rip dead thawed rats in half on accident, climb up walls, escape their tubs, try to scare me in strike position, the usual snek hooligans.
