Rats are very intelligent and social creatures, thank you very much.
I don't know who this girl is, but I could have really used her wisdom when I was 26. I hope she eventually decides that boys are not rats, although I can certainly understand how Alonzo gave her that opinion. On the other hand, she should probably be grateful to Alonzo for teaching her that lesson early, so she can just walk away from all the losers she'll date in high school. Sure, she may eventually lose her streak of breaking "none people's" hearts, but they'll just have to deal with that. We'll all have to deal with it, really, throughout our entire lives. It's just that only this girl knows it.
