I am working on an class project with 3 other people, I only know one of them. I have no problem working with strangers, as long as they have good work ethics. The problem is, the other 2 seems to reluctant to come to meetings. I am beginning to think they just want my friend and I to do the work. So I plan to split from them and just do the project with my friend. What should I say to them without sounding like an a*hole douche?
