Yeah there's a type that doesn't answer weird numbers, or numbers that aren't saved on their phone. I first thought it was only girls but then there are guys who don't answer unknown numbers.
Also, what about those who miss call you and then when you call back, they pretend like they never called >_>. YOU called me you effin' idiot!
Kaman fi the type of people who call from their parents' phones when they've got no credit, and when you call back their dad/mom picks up and you end up in an awkward situation: "Errm, can I speak to Mays please. It's Shadi." Mom: "Who the flippin' **** are you?". *Dial tone*
