"Whats the best way to wait for a few seconds?"
I find that tapping my foot works well. Sometimes I try crossing one arm over the other across my chest. Or occasionally I'll stand with one hand in my pocket so I don't look like some freak standing there with both arms just dangling at my sides. If I'm sitting at the time I might try the always popular resting of one hand on my thigh while I rest my chin on my other with my elbow on the arm of the chair or table.
