Tiberius tends to just chill and observe when I handle him. Whenni give him to others he's all like "RUN AWAY!" it is actually kinda funny because growing up I was terrified of snakes now I am absolutely fascinated by them. I think it is subtle things that the snake notices such as scent and a way someone moves Maybe even particular sounds someone makes like when I grab the feeding bin and he realizes he is in it it is on. I dunno I'm not really a scientist lol
