Back in the day as a teen (18ish), found phone bills hidden in a kitchen drawer, in my GF moms house...
Seen a number dialed and multiple conversations, around times I wouldn't have been around. Had a hunch it was an ex, that came home, recently. He got money wit her sis' BD.
I asked her sis' BD to use his phone, did my due dilligence (some hoe shyt)...went in his phone book, and matched the #s.
Confronted the bytch and charged her to the game, shortly after. I had did my own dirt anyway. The game ia cold, but its fair.
