In case you thought that the Advisor and other adults put the Crew's calendar of events and other program items together, then think again. Adjustments are just a way of life for teenagers when you have school, family, church, cross country, football, basketball, wrestling, soccer, tennis, ASB, a part time job, a paper due, marching band, wind symphony, jazz band, brass ensemble, piano recitals, tutoring sessions with the young ones, and this little thing called Venturing. Add to it when your Venturing spills over into staffing other Scouting events that need workups. Necessarily, you have to learn to be flexible.
The Cabinet gets to wrestle with the conflicts and juggle all the calendars of two dozen families. Do they get it perfect every time? Not always. Do they get it right most of the time? If you don't think so, please run for office and serve a year as an officer. At the least, volunteer to be an Activity Chair for an event and ensure that it has no date conflicts for anyone. Your Cabinet works for you, and there's no better example of the struggles and joys of Servant Leadership.
