How to convince my principal and teachers to have an end of school year dance?

Firstly pick a teacher. He or she must be "convincing" . The teacher that likes to get people involved. Talk to them of the benefit of school dances and why the end of school year one would benefit many. Tell them that it gives you something fun to remember some one. Ask for pointers and say it nice and look nice that day. For some reason teachers become impressed. Tell her you are going to take points to who thinks its a great idea. After she agrees, then ask your friends or others at school who thinks its a great idea. Take tally's and have them write their name down. Then go to the principle and write up a typed paper why you think we should have a school dance with the ballots. Then she probably will approve. Good Luck!
