According to a news report, a certain private school in Victoria, BC recently was faced with a unique problem.

A number of grade 12 girls were beginning to use lipstick and would put it on in the bathroom. That was fine, but after they put on their lipstick they would press their lips to the mirror leaving dozens of little lip prints.

Every night, the maintenance man would remove them and the next day, the girls would put them back.

If you were principal of that school, how would you have dealt with this problem ?
