The other day, my younger son found a small, wooden box in the storage. He came to me and asked, "Daddy, what's that? Can I open the box?"The first glance of the old box reminded me of my old hobby (i.e., coin collection). This box was my treasure. I opened the box, checked many coins, and closed the box － that was my routine at that time.
My son and I opened the box for the first time in decades. What surprised me was I still love old coins. They varied in terms of shapes and materials; a round or square shape: silver, copper, or gold: small or big ones.
Unexpectedly, my son was not interested in these old coins. This may be because he cannot get candies with the old coins.
