When my sister was in her late teens and my sister-in-law and I were in our twenties the three of us went on a camping trip with my mum's truck and camper. We found that we were getting an unwarranted amount of ogling from the men folk and what we felt were some equally antagonistic glares from the women at every camp site we visited. We couldn't figure what it was about us that was eliciting either reaction. None of us are hard to look at but we are hardly playboy material. It wasn't until the last day of our trip as we were packing up to go home that it dawned on me that the sticker on the back of my mother's camper was the culprit. It had been put there by a friend of hers who was a real estate agent. It said, "By appointment only"!
