I've never been so embarrassed in my life — not for the conversation or the topic, but because Dad felt it necessary to chat with me and my middle-school best friend.
Jeremy came along with us for a convention in the Bay Area. At this convention, I start making out with this chick in the hot tub while Jeremy's swimming laps in the pool. Then we all hear, "Get up here right now," from this head hanging out the window.
It was her mom.
She goes up to her room. Dad stopped Jeremy and I as we got back inside. He just glared at me, silent, and directed us to a table away from the hotel bar. We're still dripping wet from when he sat us down and bought three slice of cherry pie (warm apple was gone, I guess).
Dad reminded us of the nuts and bolts — we'd both known since we were seven or so since he lived on a farm and Dad is an FFA advisor — then went into the implications of STDs, importance of condoms and a much longer speech about being respectful to women.
Never saw the girl again, and more importantly, never ran into her mom.
