John: What's up with Deb? She was so blunt to me yesterday when I saw her at the mall.
Deb's Brother: It's not personal, bro, she's just got her rectal gates up. . . you know she's just getting over a bad breakup
John: Yeah, I guess she's feeling extra touchy these days, eh?
Brother: I'll let her know you're cool so hopefully next time she'll relax with you
