Still Happens when you get older

Still Happens when you get older I am 49 male working in a middle management, operations position. Today during a conversation between the two of us, my co-manager began imitating a Joe Biden stutter and commented how stupid he is. Once he saw the look on my face and remembered I stutter a bit, he backtracked and tried to apologize. Politics aside, when someone does this type thing, it really lowers my expectations of them. He is just a gross individual and I feel sorry for him and the people he surrounds himself with.
