When you forget your homework, I scold you. When you write the exam well, I give you a star. I will teach you everyday at school. Who am I?
I wear a white coat and when you are sick, you come to me. Some days I give you medicine, other days I give you injections. Who am I?
I am the main man in any restaurant/ hotel. I am not the waiter, but his boss. I cook delicious food for you, but I am not your mom. Who am I?
School is your second home, so maybe I am your second mother. I punish you when you are wrong, and appreciate when you are right. Who am I?
