Don't judge a book by its cover

The proverb in the title describes some people here in anderson. Some people look nice and kind but are actually mean and selfish. For example, (I will not reveal the name and class but name these people as He or She. Its up to you to guess who!) He is a prefect who is a P4 and takes care of class 4.?. She is a P6 girl who has gone on overseas learning journey with me and is quiet irritating. What else can I say?! Well, if you have any suggestions, e-mail me at hjbumanlag@yahoo.com
