I Always Remember To Have Eight Dollars.I live in the upper peninsula of Michigan, but I go to university in the lower peninsula.
That means that every time I go home I have to cross the Mackinac Bridge, which is a toll bridge and costs about four dollars.
I went on a volunteer trip once, when I was younger, and my leader paid for both our vehicle and the vehicle that was behind us, just as a random act of kindness, and it kind of stuck with me.
So ever since, every time I cross the bridge I bring twice the cost and pay for the person behind me. It always brings a smile to my face that I can do these little things for people.
