What kind of personality would a cactus have?

Is it short-sighted to think they would be crabby and aloof? It's not like they get many hugs so who could blame them for being a little discontent? Unless they hate hugs... Maybe they are pretty pleased with themselves... Well, THESE cactuses are crabby, no doubt about it.
