Sometimes an antique is still in use.
If you remember how exciting a little mechanical ride could be when you were a child, try to keep some coins on hand to indulge your young children.
If you don't have young children, consider keeping coins for offering rides to other children whose parents are tired or don't have what makes those little rides go.
If you don't remember being very young, for just 20p (or 50¢, or your local equivalent), if you're lucky and open to growth, you could live vicariously through another young person.
Patience, generosity and kindness make a person better.
A patient, generous, kind person makes the world better.
Plus or minus
