Nothing is better in life than having great friends that you can be yourself with. Or in this case, not yourself.
As you get older and busy raising your family, you will find making friends is more difficult than it once was. Finding friends that you not only get along with but also your significant other gets along with...well that's a whole new level of complexity no one ever prepared me for in life. When you find those other couples, appreciate what you have because my experience tells me those are not only important but rare friends to have in your life.
