It's the scene where Sadness timidly asks Joy if she can come down with her to the Memory Pond. In response, Joy takes Sadness' hand in hers and tells her friend, 'Of course! Remember Sadness, wherever I go, you're coming too.'
When I heard that, it reminded me of how some people fear being too happy because they know sadness might follow. That's not how life works, nor is it true. One doesn't follow the other because they always travel together, side by side, hand in hand.
Joy and sadness are like train tracks. Even on the saddest days, if we look closely enough and allow ourselves to experience it, there's always some joy. Similarly, even on the happiest days, like the birth of a child, a wedding, a graduation, a championship, or a promotion, when we remember someone or something missing, there's always a hint of sadness.
That's why when we say we're grateful for life, we can't just be grateful for the joyful moments; we must be grateful even for the sad parts. We must be grateful for everything. Joy and sadness carry us (or we carry them) as we move from one stage of life to the next.
