The correct answer to this open question is the following.
There was a time when I had to make a difficult decision and my social background and personality impacted my choice.
I use to hang out with what I considered to be very good or close friends. We were part of the football team.
Everything was good. We used to be very close on the football field, in school, and in social life.
However, one day, something ugly happened when one of these guys had a problem with a group of students. Indeed, they were immigrants and they were what we call "geeks." They were shy boys and girls, from another country, did not like sports, and behave differently from what is common for an American student.
This guy treats those students very badly. He was rude, disrespectful, and aggressive. I knew those immigrant students and had a decent relationship with them, and honestly, I didn't like the way they were treated.
So that day I had to confirm "my friend" to stop his behavior. Of course, he did not like my position and fired back at me. My social background and personality made me defend what I considered was right. Every single person deserves respect, no matter the color of skin, race, or social class. That is what my family taught me and that is what I believe in.
The consequence was that those teammates started to be cold in their relationship with me. I understood. They had their beliefs.
On the other hand, I gain new friends that accept me the way I am, and by the way, they help me a lot by explaining what I do not understand in class.
So, my personality and conviction made me lose some "friends" but at the same time, I made new ones.
