"The web of our lives is of a mingled yarn, good and ill together." - William Shakespeare

As I had to buy some medicine today, and when I opened it, I began to wonder . . . Do you put the cotton back into the bottle? How many times? Until the last pill is gone? Or if not, what do you do with the cotton? Throw it away? Use it like you would a cotton ball (to take off nail polish or something along those lines)? . . . So tell me, what do you do with the cotton that comes in pill bottles?
