Agreed. Always a negative side to those that think negative.

Many of the High School bands in our district have marched at Macy's and/or the Rose Parade over the years. Fundraisers.
When both of our DDs were in HS choir (that school has consistently been ranked near the middle of the top 100 High Scools in the nation over the years since before our kiddos all went to and graduated from there, and still is) we worked all those years at UT concessions to help raise the money for the year-end trips. The kids worked their behinds off right along with us aduIts. I don't remember any of those that volunteered rolling their eyes. Maybe, only the ones that didn't participate in the fundraising. You can roll your eyes, or get off your butt. 'Cause, you're right, the students are more than honored, as well they should be, and the parents, IMO, should be more than willing to help that dream come true for all their kiddos hard work. Why would you encourage them, supply the money to rent/buy musical instruments for them, pay for extra lessons etc., and then get all negative about a dream of their, granted, relatively short, lifetime coming true...?!?!?!?!
Seems to me, If your going to encourage and push them, a good parent should be prepared for the "consequences" that could likely follow.
