Interesting post. It has always amazed me to be in the park or mall to watch people and see so many couples that look alike. Older married couples tend to resemble each other more. They develop the same facial expressions, hair cuts, mannerisms and they walk the same. They respond exactly the same and when they eat their styles are very similar. A good friend of my gf wanted to introduce us to her new bf and we met for dinner. They have been going together several months and I sat there in shock. Their hair color was the same, their eyes, the way they talked, their facial expressions...they were like clones. They had the same dry conversation style. It's like they were brother and sister...but they were not.
