15 minutes?

Oh my! I prepared a 45 - minute message for a speaking engagement but when I saw the program today, I was given only 15 minute talk! How can this be? The one invited me said through our verbal convertation that I will speak to the parents and students during their school family day on the topic " Effect of Parents on their Children". This is a broad and very essential topic,how could the program coordinator allocate such a short time? I began to be irritated when I saw at the end of the program that they have a Family Disco from 6 - 8pm. Tsk! Tsk! Tsk! Calling the School Administratior of Sacred Heart of Jesus High School!
