When I was 20 and newly engaged, one of my relatives stumbled up to me at a family party. Just tipsy enough to be totally honest, she pulled me aside and slurred in my ear:
"Just make sure this is something you really want," she said, referring to my engagement and future marriage. I smiled politely, hoping to catch my fiancé's eye and wrangle my way out of the conversation, but she continued. "Your 20s are such a special time. Make sure you really get to enjoy them."
