I for the most part agree with Mike. The exceptions being, that my husband swears my pastel likes me better. He will try to get back to me when my hubby holds him. And the next being, that for the most part they aren't really "nasty or mean" except for a female pastel I had. She was an absolute witch, and would strike for no good reason. Maybe she was part vampire and liked blood.
But yes, more likely for a single snake to be in a glass tank. Soaking in a tub is not good, no, they don't like to "swim". And they do seem to respond a bit different to different people. Maybe not because they "know you", rather than different people handle/hold them different, and they are more comfortable with one over the other.
