Both of my snakes come to see me on feeding days. They come over to me so I let them "sniff" my hand before I pick them up to take them to the feeding cages (I feed them away from the main cage area so they dont think I'm dropping a mouse in when I want to hold them). Reshmar, my male snake, even comes to see me whenever I come home. They both have good envirnments and are very healthy.

So I think it's fine that a snake should come to see you.
