"DISAPPOINTED"

While we were writing the lecture, my friends Jangot, Mel, and Boy were beside me. They are my close friends. Jangot had a cough and cold, but he/she still went to school even though he/she was sick. While we were sitting next to each other, Jangot suddenly coughed and didn't cover his/her mouth, so his/her saliva landed on me, which made me disappointed.
