When your actor is talking to the camera, don't use a dolly move.

When a character is talking to the camera, the camera is meant to be me, the viewer. So if you go and put a move on the camera, it gets freaky. Like I'm sliding across the living room or something.

Don't do that.

I'm serious. It makes me uncomfortable.

Not to mention how hard you make it for the actor, talking to a moving target.
