No, I can't explain it but it I know it's true. When I was in H.S. my friends (and even people I didn't know) would say- "your headlights are on" or "your on high beams". In any case, I knew they were referring to the fact my nipples were poking, and clearly this was an undesirable thing in their view. I just wish I could have thought of a clever thing to say back to put them in place!
