Why my crush who rejected me (ghosting/ignoring) me staring at me?

My back was turnt from him at the meeting but when it was over I got up while leaving I see him and a girl looking in my direction mind you they was watching me the whole time, until I left the room. But like why are you both watching me and not listening to what the person is saying about caps and gowns for graduation requirements.
