Me and two of my cousins used to go to the bar every day at four and get a Guinness each. Then I moved south. I missed my afternoon beers with my cousins. So I find this local bar that had Guinness. I decided then I would come back each day at four and have a round in memory of the times with my cousins. After I had been doing this for a few weeks, the bartender asked why I always come in each day at four and order three Guinness. I told him my story.
A few months later, I went in one day, and only ordered two Guinness. After a week of this, the bartender asked me if anything was wrong, if something happened to one of my cousins. I said "No, my cousins are fine, but my doctor told me I needed to stop drinking alcohol. I still enjoy time with my cousins, why should they stop drinking?"
