I can relate... I used to teach tennis and when my two boys were old enough I had them out on the court. After a few years they got pretty good. When they got to be about 13 I started to really push them... ERROR. Now, I just yell "Good Shot" and go pick up the ball. I consider it a good set if I don't get hit by their serves - damn kids, no respect for old people
They are now both over 30 and play golf. Problem is that they are both 6'5" and hit the ball out of sight...... now I just yell "Mulligan".
Gettin old is crap!
