Tit for tat.
I have some belief in karma and being rewarded for not fucking with people when they need help. If they don't really need help and you can get a laugh, that's legit. I hate when I'm asking a legitimate question to someone important (boss, landlord, dean) and they joke about it. Give me a straight answer fuckstick, it's your job! Tit for tat comes into play when I write bad reviews for people or keep the address to send random shit to.
