Silly Bandz and Gum

That is a weird title. Sorry. What these two things have in common is that at our house they are used for trading.
For example....one silly band given to your sister equals that sister moping your floor for you. (that one was eryn's idea)
Also, one stick of gum given to your sister equals that sister setting the table for you. (that one was my idea) The funny thing is, the younger girls are the ones getting something and doing a job for it.
