Once upon a time...
I was on vacation with my parents and my brother and sister. We went for the day to Aspen to do the Alpine slide. It was a lot of fun and as we were leaving, Mom and Dad said maybe we could get some ice cream. Really nice of them right?
Well, then Rachel and I had to ruin it. I thought it was over by the "x" thing and Rachel was sure - absolutely positive that, no, it was definitely over by the "y" place. We argued about it. Until Mom said, "Fine, we just won't get any."
I can't be sure, but I think that was a pretty good learning experience. When ice cream is on the line - play nice!
