Just an aside that I had to share with the world.
Earlier today, after my optometrist appointment, I was walking back to my car in an underground parking lot (the open air free parking was full). I walked down the trolley (“shopping cart” for the American readers) ramp and noticed an old guy in front of me, balding and grey of hair, who every so often would take a little run and jump onto the back of the trolley to ride down the ramp.
It was extremely amusing, and shows you’re never too old to have a happy childhood.
