Your father called me at the country club to request I give private tennis lessons to his girls.  He was incredibly pleased with the work I did with your mother over several weeks last summer and now he wanted my attentions on them.  I had seen them both at the spa when he was out playing golf several times in the past so I cleared my schedule to start their tutorial.   When I arrived at the house he was already gone but a hefty little check lay on the counter with a note from the girls they were out back warming up.   When I stepped back to the secluded court I could see that they knew how I handled lessons with their mom as well.  It was going to take a good month probably two to work them out properly.
