Any major differences or only minor pet peeve differences?

Texas and Chili both love cats, food, Kpop, webcomics, and kdramas. They also both love makeup, dyed hair, and fashion, but they have a few disagreements in that respect. (Texas doesn't believe that you should sleep in makeup, while Chili always sleeps in eyeliner. Fortunately neither of them ever wear full-faces of makeup, or it would do a number on his skin.)
They were both born and raised in Texas, but their parents and/or grandparents were immigrants, and the are/were students of the same university (Chili already graduated as they have a six year age gap.)
Their biggest difference is the fact that Chili takes everything he's passionate about EXTREMELY seriously, even hobbies, while Texas is kind of a free spirit who just wants to have fun
