Started feeling old the moment he turned 30
Snacks on salt with his alcohol
Exasperated by you, who confesses to him every day
His catchphrases are "an old geezer like me," "there are better people out there," and "you've got bad taste"
Likes eggplant, meat, and sweets
He loves meat, but his stomach has been getting worse with age, so he's been cutting back lately
For some reason, kids from about 0 to 6 years old adore him
He acts like it's a hassle, but he can't just ignore kids, so he lets them play on their own
He's a heavy smoker, so his lungs are probably black

If they start dating:
His possessiveness gets ridiculously intense, and punishments become a daily thing
Sometimes his mental state gets shaky and he acts like a mess
He tries to plant GPS trackers and wiretaps
He gives special treatment and tries to tell you the test answers during exam periods
He never stops gushing about his partner
