While waiting in line at the bank, I overheard two women
discussing a little ice cream machine. Rock salt is what you
put in it and then you had to stir it for a long time. One woman
said that she would be too lazy to stir it for a long time, and the
other one said that is why you invite friends over.
The conversation concluded with the thought that there would
not be enough ice cream for the people invited over to stir.
The solution was easy enough as it was stated that was the time
for the invited company to go home. Problem solved.

To create and eat homemade ice cream”.
