Make a Day

I have always been fascinated by the type of things that can cause someone to say, "You just made my day!"
Take last Thursday for example.  I was on choir tour at Six Flags, an amusement park in California filled primarily with roller coasters.  The park also had a merry-go-round and a few other simple attractions.  One of the rides was called "Tidal Wave."  It was a ship that rocked back and forth like a pendulum, just like the "Tidal Wave" at Lagoon.  Right before going on this ride, I and my choir friends decided that whenever our side of the ship tipped upwards, we would sing the three notes of a music chord in an operatic manner.   Sure enough, as we went up, the seven of us breathed deeply and belted out a resonant "Laaaaaaaaa!" with each of us singing our preassigned notes.  When the opposite side of the ship went up, the random, non-choir people on that side merely screamed, as if trying to out-do us.  Sure, they were louder, but we had the advantage of harmonious awesomeness.  This contest last throughout the ride.
"Laaaaaaaaa!"
"AaAaAaAaAaAaAhHHH!!!"
"Laaaaaaaaaa!"
"AaAaAaAaAaAaHhHh!!!"

When we got off the ride, the employee who had been running the ride declared exuberantly, "Ohhh!  You just made my day!"
"Wow," I thought to myself.  "It must be really boring to work here, press a button all day, say the same things over and over, and watch other people have all the fun.  I'm glad we could make something memorable out of the monotony."
This incident made me ask myself, "What small and simple things have made my day in the past?  And what does that even mean?"
I think what makes your day is the one thing that you will always remember even after the rest of your day is forgotten.  If I can be a "day maker" for other people throughout my life, I don't think I'll need fame or riches or anything else.
