For the past several years, the school has asked a nominal amount ($50) for various charities, in return for which you could wear jeans every Friday (36 times). Jeans is a small perk, not really necessary but enjoyable.
This year, they are asking for less money but each $5 gets you one jeans pass.
Guess who isn't giving any money?
I will just do without wearing jeans. And they can do without the "contribution."
