DIA 341:

They have the perfect life. They have it all and take for granted. How can they live life like that, I asked? Like there's no tomorrow, or yesterday. Life is all of it, not just the present. Regrets are not only about good stuff that could have happen but also about bad stuff that happened already. You'll grow, you'll understand, one day maybe, and I'll be here, where I've always been, watching over you.
