well, just speaking from personal experience, they are definately friendly. the two that i have are about the sweetest things you could ask for. they love being handled and I've only been bit once (totally my fault, during a feeding).
at the stage tehy're at (a little over a year) they're a good size and usually friends tat are scared of snakes or have never been around a live one before are up to holding them, even if just for a little while.
so yes, loveable an peaceful. just keep them happy.
