Also, she was more than 30 minutes late for the meetings which we were supposed to discuss our presentation. And she didn’t even say sorry to us. Or she just changed the appointment at her convenience. Although she does not really know of my part which I am going to present, she has been bossy and just kept ordering dismissively what you do or do not. When I do not want to follow her commands, she said like “I’m going crazy, why are you so stubborn” like a dictator. I was not so close to the other girls in our group, and samanda and bursa were best friends. They made fun of me doing group meeting, and laughed at what I researched for the presentation. I literally had to “fight” for my part to do what I want to present. It’s been really stressful to me. and I'm really glad that I've finally done tomorrow. when I talk about my opinion she pretends not to hear or just did not pay attention on purpose. I know it sounds I just say mean things of her but It’s been very hard to complete this project with her I feel like I have been being bullied. I really regret that I made a group with them. I feel a bit better that at least I can talk about it to you. and for what I've done for the project is I researched about "what causes aids" of population, education, and superstition. I think I learned being patient. and I feel a need to have my own country's friends not to be bullied.
