Snakes 'knowing' you?

I don't know if my snakes know me. I do know, however, that they act different when I hold them then when friends/family do.
It's even more apparent with my leos.

I haven't had my girl for too long but she seems to know the difference between me and my wife as well as our nieces when they come over. She wanders all over me and when she realizes she's near my wife she'll coil up or just stay very still then come back to my lap. The two older nieces are too freaked out by her and the youngest wants so much to be comfortable with her but her and Orchid sit as still as statues when she holds her.

I think another big factor is the confidence of the person holding the snake. The snake might act more timid and jumpy around friends/family because those friends and family members aren't as used to handling snakes.

I have one friend who doesn't own any reptiles of his own but he claims he's the "ball python whisperer" after lots of encounters with other people's pets, including a time when he helped a friend move her entire house while her snake was around his neck. My snakes act more calm around him than they do around me, and I handle them almost daily! My bitey male baby turned into a complete sweetheart in his hands. The only snake he's ever owned was a burmese python 20 years ago that he pulled out of a car engine.

IMO you're nuts haha.

I pass mine off to my kids, kinda let them crawl from my hands to theirs and all 4 want nothing to do with them.
I have to plop them into their little hands because they take a smell at their grubby little sandwhich clamps and say nope.

I think they can learn who we are, but it is more of a safe person/not sure type reaction. I have spoken to people who keep rattlesnakes, and they report that the snakes will stop rattling at them after they have owned them for awhile and the snakes have become used to there scent and them being around the cage etc (wild-caught snakes as well). However, if someone else comes in the room, they will go back to rattling at at them.
