I was getting on an airplane the other day and was following two young women down the isle of the plane. One woman held an infant and the other their tickets. They had stopped and spoken briefly to the flight attendant upon their entrance to the plane and seems for some reason to be struggling to find their seats. One of the moms turned to me and asked me where they were suppose to sit. The young mom was standing at row 12 and showed me a ticket for seats 12 D,E and F. At first I was a little confused. But then it all became clear. Both moms were illiterate.
