Drama isn't isolated to TB. Rec ball has drama, too.
Youth sports* of all types, and at all levels, breeds drama. The OP presents an example of the common issue - parents who think their kid should be getting more than what they are getting.
* "Sports", in this case would include pretty much any activity where there is competition of any type.. "My Suzy should have had the lead role. She's a way better actress than Sally."
very true, my lame attempt at humor.
