I've got one who is super friendly and outgoing, and another who is shy. Domino looooves everyone and is willing to hang with anyone who will pet him. Chewy is very shy, but once you've been to our house enough times, he'll come out and let you pet him. He knows my in-laws well enough that, when we're gone, he'll stand on them for attention! When my friends come over, Chewy will 'flirt' with them (i.e. he weaves himself around this corner at the top of the stairs, rubs up against the corner, arches his behind on his tippy-toes, and flicks his fluffy tail. He's such a tease!
