Andre is like that to everyone in general due to past issues. However he had it drilled into him from a young age to be a good person to women. Though he doesn't strictly live by that he does give girls a bit more leeway than boys though only by a small margin. And he isn't hostile to anyone who just goes up and says hello to him he'll say hi back as long as you don't keep poking him or do so in an way that he finds obnoxious.
