Baka inakala ng Dad na "mamasan" ka at may mga alaga kang pwedeng irekomenda sa kanya, Cathy. JK, LOL
Seriously, if you haven't done so, just return the money and tell your "friend". If he's really your friend, he will understand and have an open mind about it, tapos bahala na sya to confront his dad. If he didn't believe you, then he's not your friend after all.
The dad could be a "player" during his younger days. Maybe it was his practice to get easy *** in exchange for money nung bata bata pa.
