i see it like this, dogs,cats,birds,sugargliders and alot of other can and do so why is it impossible to think snakes cant? i have a carpet that basically tells me when she wants out and to be held. she comes to her door and lays her head up on it and when i see her do it i open her door and she almost literally craws up my leg and hangs around on me untill shes tired of it. once shes ready to go back in she gets restless if you wanna call it that and she goes back down to the floor and over to her cage and gets back in it if the door is still open which it usually is because her cage is 6ft tall 4 ft wide and 2 ft deep. oh and its home made and i got it very cheap thats why she has such a huge enclosure to hang out in lol.
