Forever is a concept you only truly understand once you've found true love, and I don't just mean romantic love. It came to me as the result of a beautiful loving lady, who melted my heart and made me see I was worthy of being loved too. As we grew together, forever became something that transcended life, and made me realize I'd love her beyond the concept of death.
Oddly enough, I never need to bring up the fact that one of us might eventually outlive the other, because my darling is all "Life-Oriented". And so we both remain positive, and work steadily towards our combined future.
