I dont know if my snakes really recoizze me but when i hold them they are very relaxed and they explore around, but when other people are holding them they seem more tense and they just kinda sit there.I think after time they reconize my smell and they know im not going to hurt them so they trust me, but with somebody else....they are tottally new and they dont really know what to think

so i think its mainly based on smell
