Nostalgia's a helluva drug. In moderation, fun, but you can overdose. It's difficult to strike the right balance, but if you do, for a brief moment, there are personal truths you can uncover. Parts of yourself that you can unlock, often because you need to do so.
I'll live another lifetime before I'm as old as these characters, the stars of the Before trilogy in an alternate universe. I only hope that in this next lifetime I can create enough memories worthy of being remembered.
