Do angels exist

It was the first day of new semester, everyone was entering the college . There was a lot of shouting near the gate of college . Everyone was really happy . The students entered their classes for the very first lecture . As the teacher entered the class everyone greeted him . I was a little nervous at the starting .But then I met Sofia , she was my best friend in school and I felt really comfortable with her . The teacher introduced himself and he asked the students to introduce themselves . The fifth turn was mine I was really nervous. As I stood I was shaking I wanted to speak but there were no words coming I wanted to shout that my name was Zai but I felt like I was not having any voice . Then the thing happened that I was most afraid of , Aisha came to class and shaked me forcefully and told me to speak up but i was too frightened . Then Sofia told my name was Zai . Aisha held my arm tightly and took me out of class and scolded me for not speaking and letting her feel down . She was a senior student and was really popular she was feeling shameful to say that I was her sister . I was helpless and even if I wasn't there was nothing I could have done . Cause if I opposed her , I would have been tortured for one more night . She was really angry and said ,"Who do you think you are ?"
