Bust out your friendship bracelets from the memory box, dig out your old favorite t-shirt, and blast the oldies. Today is all about honoring long-lasting bonds and the joy of commitment. Text your pals aged photographs from bygone parties, eras, and events. Write appreciation notes to anyone who’s been doing this thing called life with you for the long haul. Even if that means silently saying “thank you” to that glittery pair of shoes.
