Snake tricks

[Eric Alan]

Maybe the heat detection is what draws them out. I mean if the snake comes to you I guess it doesn't really matter how it knows you are there.

This.

Your head is the warmest part of your body (that is normally left exposed) and is almost exactly the same temperature as a rat's body. Your hands are next on the warmth scale. Nearly every behavior you have described can be attributed to this. While it can be cute when they "kiss" you, keep it in the back of your mind that they give very similar kisses to rats just before making them disappear.
