Great thread topic. My best man and I have been friends since middle school (over 25 years), played in bands together in high school and college. We lived close to each other until about twenty years ago, when he had a family tragedy. He ended up moving out west (coincidentally to the same city my other groomsman moved to), to be close to other family.
We have visited each other a few times throughout the years. We talk probably three or four times a year, and text every now and then. I build and sell guitars, and recently built him one. It was probably my most rewarding build - to know that one of my best friends will get to enjoy it for the rest of his life. Wish we could spend more time together, but so is life.
