Flight to Chicago

After we were down at the ER we rushed to the airport and made our
flight. Dahlia was given Tylenol with codeine on an empty stomach
which made her sick. At about the halfway point of the flight Dahlia
asked me how many times she had puked. The 11 year boy next to us
piped up and said "It has been 4 times but really only two of them
produced anything."
