I was sitting in my class when my friend came and he told me to get out and sit out side. But i told he that i have a group assignment and need to work on it with my group. So i left him there to call for my group members. My class was on the forth floor so i went to the third floor and leaned on a corner waiting for my group member to come out. At that moment My friend was coming down the stairs and saw me there standing, he didn't say nothing he just walked past me. I was able to tell from the way he looked at me at that moment that he thought i just came down the stairs to avoide him. And i didn't confront him for the rest of the day. We are yet to see each other. So what should i do in this situation.
