If you don't want to be stuffed into a box, the answer is fairly simple. Treat others as if they have moved on, and they will do the same for you. That bratty kid brother is now an adult. That sister whose boyfriend you had a crush on is no longer a girl competing for dates. See everyone in the light of the future. If you can identify where anyone wants to go tomorrow, you have the best chance of relating to them today. So see today as the beginning of the future , not the tail end of the past.
