Making Money From Moochers

I have three extra dollars in my pocket all because I was nice.

Apparently, I was the only one that had the right type of tape needed for the 3-D Design assignment. I decided to be nice and let several people have some. Well, one person ended up using the entire roll. By the time I was able to use it, there was nothing left! The person felt so guilty about it that I ended up getting three dollars from the person for a new roll of white duct tape!

Who says being nice doesn't pay?
