Coaches aren't anti solo-cups, and they will be reasonable if a parent says, "Hey, coach, Johnny was at a church picnic Sunday afternoon when this picture was taken." They are cracking down on the cutesy little game of, "Nah, coach. I was at the Xi Phi lake party, but while everybody else was drinking beer, I was just drinking coke out of that red solo-cup there." Don't be at the party in which coach knows that people were drinking, and be seen holding a solo-cup. Coach knows the score. Don't try to treat him like a chump.
Now back to your original question, Ironhorse. I will tell you what I don't want to hear. Some parents on here report that their coach is one of these "My-way-or-the-highway" guys who acts arrogant with the parents at the meeting. I'm adult. I won't be talked down to. That's a good way to shorten your career at a program.
