Thoughts on “a friend to all is a friend to none?”

I'm 17, and I recently started a new job. I'm not sure if this is normal, but I constantly get asked things like "who do you like more" or "who's funnier," and things like that. It seems like a simple question, but I have a very hard time answering, so I usually just say both. After a lot of pressure, I would essentially be forced to choose someone, and it would make me feel really bad for the other person. The other day, I think I made one of my coworkers upset because I couldn't choose between them and another coworker. I know it's very trivial, but it's something that causes me a lot of anxiety. I feel like in the future, when there are bigger altercations, I won't know how to deal with it.
