I don't want to make friends in the workplace, because I think there are no real friends in the workplace. Many people are for their own interests, and it is impossible to treat you sincerely. If you two don't have any overlapping interests now, you may get along well, but once there is a conflict of interests between you, it will be difficult to get along as before. There are many things to get along with each other, which are not so good. Even our friends who grew up together may turn against each other because of their interests, not to mention that you two have only known each other for a short time.
In the workplace, everyone may make a lot of efforts for their own jobs and wages, but it is also possible that you are better, and then you are envied by others, or you are fighting for a better opportunity, and then there is a conflict between the two of you. No one can say these things, so we can't treat the people in the workplace with the truest heart. It doesn't mean that we have to face one thing and face the other. You and he are ordinary colleagues, so you can get along as colleagues. There is no need to dig your heart out. You should handle your own affairs at work, so you don't have too many intersections in private.
Don't think what I said is very ugly. In fact, after you really get to know it, you will find that it is very dangerous to make friends in the workplace. If you don't have conflicts of interest, your positions don't overlap, that's all right, but once you have a little connection in your positions, then you will compete for something. What will your relationship look like? We should never think too simple about human nature. Maybe you got along really well before, but once something happens, it's really hard to say.
