My Serenity is like that, very docile, very laid back personality, she clings to you like a brooch or some other piece of jewelry and then wraps her tail like a Curly Q. :) Every now and then when she's in VERY familiar territory and it's very dark, she'll cut loose, but for the most part she just hangs on a person and doesn't move much.
I can't say I like her better or worse for it, but it is a cute quirk. :) My gliders all definitely have very different personalities.
