I don't know about all that, brianb, but I will tell you a true story...
I went on an overnight camping trip with a large group of friends. At the end of the day, many of the people decided to go home. There I was, the only female with 6 guys (1 was my cousin) in a motor home. I honestly don't know how the sleeping arrangements worked out the way they did, but I ended up in a double bed with a true gentleman. We were both embarrassed about the arrangements, because we were not even dating, although we did "have eyes" for each other. We decided to sleep head to feet.
In the middle of the night, we both woke up freezing...the AC was set to "arctic blast". So we went outside to warm up...and ended up talking the rest of the night away...and the rest of the story? We were married for 27 years, until he passed away. 8)
