Not my sister and her friend

One day my sister forgot her glasses , so I decided to catch up with her and give her them.I (thought) saw her and started yelling EEEEMMIIIIIIIIIILLLLLYYYYY!!!!!!!!But hey , she was not listening , niether was her friwend Maddy who she was walking with.So I called her louder. STill she would not listen.Finally I realized that it was not my sister and her friend it was two other girls.I was laughing so hard when I realized that the girls hair were red and black not the colours of my sister and her friends.Finally I went up to Maddy house and knocked on the door.Em opende it and I told her the whole thing then left and went to school.Please comment!!!!!!!
