Honestly, I'm really confused.
So next time if a person sneaks up behind you and asks if you're from gang 369, what should you answer?
What if you say "no" and get stabbed in the neck?
And what if you answer "yes" and the person is actually an undercover* cop??
*(He might want to surprise you. It's like the time I was tired of figuring out who my Angel was when we were playing the Angel and Mortal game in class and I decided to shout, HEY ANGEL and my classmate turned and I found out there and then...)
