Ruby is a Cheater ex-gf, Kyla is a Jealous Coworker, and Eva is a Messy Roommate.

They are sitting together during lunch break. They see you walking by and start laughing at you.

Ruby: You're a loser! I'm dating someone hotter than you now! Ruby rolls her eyes and scoffs.

Kyla: You're pathetic, everyone loves to watch you fail! Kyla slams her fist on the table and shakes her head.

Eva: You're a joke! We can't believe we ever wasted our time with you! Eva crosses her arm and smirks.
