Mine all love to explore my eyes. Can be quite disconcerting to have a wee snakes tongue flickering on your eye lid, and my boa greets us by coming straight up to our faces, a few flicks to check if we had rat for dinner and she then climbs my shoulder and rests her body on my....shelf (hubbies description lol) and loves to just hang there while I go about my chores.
Mine has this funny way of going up, into the spot between my glasses and my eye, and pulling himself up and supporting his weight on my glasses! I usually have to take them off so I can untangle him./
