During their son's 18th birthday party, George and Lisa hand him an unusual envelope.
"Tom opens the envelope and pulls out a sheet of paper. He begins to read with a smile. Then, looking at his father, his face takes on the features of wonder. George crosses his arms, as does his mother. The boy's face bears an expression of horror. A trickle of sweat disfigures his face. Silence falls. Everyone leaves. Tom is left alone with his parents.
At first it seems like a joke, then Tom realises that it is not.
"What makes a child mature is the fact that his or her parents take him or her for granted".
