After several years, my wife finally agreed to go backpacking with me. I picked one of the most beautiful places to hike that I know of. We hit the trail and I noticed she was swatting at mosquitoes almost instantly. We arrived at our destination and I looked at the beauty of the lakes and trees. My wife was looking at all of her mosquito bites and giving me dirty looks. She asked if I had any repellant and well, yes I did in fact have repellant. I gave it to her and after she had put gobs of it on her body, the mosquitos continued their feast. Looking at the repellent tube she noticed that it was ten years old. More dirty looks. Needless to say, we hiked back out and went to the nearest town and got a motel room -- with a jacuzzi. We counted over 100 bites on her. I had none. After going thru chemo, the bugs don't like me. She didn't either. I don't even ask her to go hiking with me anymore.
