What did we do, but speak two sweet words to someone! In our youth, we made preparations for death.

This couplet speaks about the profound impact of love or deep connection. It says that just by sharing a few sweet words with someone, the poet felt like they had already prepared for death while still in their youth. This isn't literal death, but a powerful metaphor. It suggests that such a deep emotional investment or vulnerable act, perhaps in a relationship destined for heartbreak, felt like an end to their carefree youth. It's as if opening their heart to love brought a sense of sorrow, sacrifice, or a loss of innocence, making them feel like they aged or faced a significant life-altering event prematurely, preparing for a metaphorical death of their joyful, unburdened younger self.
