There's an experience threshold that you can never hope to impart on anyone unless they just go through it for themselves. It's true for addiction, it's true for love, and it's true for grief. It's why I very rarely ever give advice, because in the places it matters most, you'll just have to see for yourself.
With that said, I find an incredible sense of comfort when I reach one of these thresholds and get to remind myself "yeah, your parents were right." And lately, that’s led me to one of my most genuinely comforting thresholds: that I know nothing.
