i agree that a lot of it happens at the younger levels and/or gets blown up. My cp's(youth) tends to get eye rolls a lot. for example, at NCA this year she told the team going on in front of them "good luck" and they did reply with "good luck" then rolled their eyes as they turned away. She reports this happening quite frequently when she is trying to be a good sport...LOL. i wonder if the sincerity is questioned when kids try too hard. At UCA last weekend there was a team that stood and clapped on the awards floor for EVERY team when they announced their place. i truly believe that they were sincere, but judging by other's reactions around me, they seemed to think it was more of an "in your face" thing. i think it's best to assume good intentions until you're proven otherwise.
Last year going into day 2 of NCA my cp's mini team was in 2nd place. Our gym owner passed the 1st place team in the hall in a prayer circle, their coach was praying for our team to drop their stunts. That was bad. i couldn't even comprehend prayer for someone to do bad. that can't bring you good karma ;) but it our 3 years in all stars and one on the show team that's the only really really obnoxious thing i've experienced.
