You realize that our mistrust of the future makes it hard to give up the past. We can't give up our concept of who we were. All those adults playing archaeologist at yard sales, looking for childhood artifacts, board games, CandyLand, Twister, they're terrified. Trash becomes holy relics. Mystery Date. Hula Hoops. Our way of getting nostalgic for what we just threw in the trash, it's all because we're afraid to evolve. Grow, change, lose weight, re-invent ourselves. Adapt.
