You should say:
– Who he/she is
– How you know him/her
– Why you disliked him/her at first
And explain how you feel about your friendship now
One person I initially disliked but later became friends with is my current classmate, Linh. When I first met her, I thought she was arrogant because she didn’t talk much and always seemed serious. We worked on the same project, and at first, we had a few misunderstandings because of our different working styles.
However, after spending more time together, I realized that she wasn’t arrogant at all—she was just shy and very focused. She always submitted her part of the work on time and helped others when they struggled. We started talking more, and I discovered we had similar interests in music and movies.
Over time, we became close friends, and now I really admire her for her honesty and reliability. Looking back, I’m glad I didn’t hold on to my first impression. This experience taught me not to judge people too quickly because sometimes you just need time to understand them better.
