My wife called me when I was out with one of my friends the other day and she told me that she was going to be running to the store.  She asked me if I needed anything, and I told her that I just needed some more of the melatonin sleep aid.  She was a little worried that I was getting addicted to it, so she told me that she would rather not buy it.  I asked her again, and she refused.  I knew that I would have to go get it myself if I really wanted it.  She would not be happy.
