Recently I received an email from a soccer coach, asking for advice.  This is what he pointed out:

“My pet peeve at the moment is parents yelling instructions at kids. In the last week all three of my kids have had parents (not me!) yelling instructions at them and what is even worse is that the instructions have been wrong!!  I could go on and on, but this has to be addressed.   Cheer yes, instruct no.” More info
