I agree that in the real world not everything will work out the way you want it as in working with people you are friends with. But it is also important to work with people who you know you can get along with or have good people skills. If people in your group do not know how to work or have a professional relationship this can cause a big problem as delay the project from finishing. I understand that sometimes you might end up with people who you do not get along with because in the real world you do not always get what you want but it is important that the people that are hired to work not only know the material and have the right skills to get the job done but also have good people skills and can get along with anyone they might have to deal with.
