A childhood belief about in the street

When I was little my dad used to take my younger sister and I to the Rose Garden in Marquette Park in Chicago. We'd roll up our pants and jump into the fountains, collecting quarters that my dad pointed out which mysteriously seemed to keep appearing in whatever direction we were walking. We believed the people who ran the city of Chicago put them there for our benefit, because they knew our family needed the money. I remember once feeling incredibly charitable by offering my dad a couple of the quarters I'd found. It wasn't for years until I realized he'd been the one dropping them for us.
