Have you ever done a good deed

So..I paid for a co-workers parking for the day at work because she forgot her purse at the office..only $5...When I left at the end of the day I noticed she had a parking ticket on her car...turns out I inputted her licence plate wrong by 1 number when I inputted it into the system..even though I'm sure I inputted it as she told me..I just grabbed the ticket and paid it..$75 later -__-
