I overpaid for parking this Semester

For Some reason I wanted a picture to remind me back in November

Parking at my College costs $40 a semester or $4 a day.
I didn't pay for the $40 parking pass.
It was my first semester of College and I just said hell with it.
Instead I paid $4 every class, two times a week.
That total came out to over $100.
At the end of every class I put my parking pass back in the machine since I have to pay for an all day pass.
Just figured I'd pay it forward you know?
Fast forward to today which is the last day before Winter Break.
As I approached the machine to put the pass back in I saw a girl a couple rows up walking towards the machine curious at what I'm doing.
I'm shy so I run and get to my car.
Next thing I see the girl walking two rows up from me, gives me a big smile and a thumbs up.
She's holding the pass.

tl;dr
I overpaid my 1st semester parking fees by over double...
...and it was worth it
