Is it true that a teacher would tell a child yes but if another child ask the same question the teacher would say no?

well sometimes when in school my homeroom techer would do that. well today is my birthday i was born on 4/1/97 so i got a cute vera bradley tote bag. Now at school we have this new rule that if you have a book in a bag that's consider book bag but this girl who is has one said that all she has in their is her twilight book and agenda. watch me come in to school with that bag and my backpack and the teachers will go to puyt it in my locker and if i tell them its a purse they be like let me check and if thers just one book inside they will go to put in my l0ocker. But what should i tell them? Should i tell them that i have a book bag in my locker? Or should i put things in it that will look like its a purse? well i hope that someone reads this and rates it good if you have to rate these answers
