thats what i do -- i have tried explaining competitive matchup -- i even went so far one time and told my partner to just stare at the block lol -- not helpful but he looked like his head was about to screw off his shoulders and roll away. I guess I see this more when i work a non varsity game.
I know a bad habit of mine i have to stop - walking and reporting
-- I get annoyed if i havent finished my reporting by the time i get to the normal reporting spot and that only happens when the book isnt paying attention
-- but I do use 1 hand not 2 and a game recently I had to wait and look at the official score book for almost a minute -- I didn't do what i usually do which is say something I just stood there waiting -- finally she looked up and blushed, I smiled and it never happened again.
