I mostly just burp, fart, and pick my underoos out of my crack a lot...you can ask Night Fly to confirm. (I know, it takes a special person to love someone like me)
I normally spot my partner and try to not think about anything. We normally talk about the people with shitty form and how they are going to get hurt. But when it comes time to get under the bar My mind just clears and I before I no it I am done and switching around plate and spoting. The only time we really take long enough breaks to talk is when we squat and then it is just so we can get our mind off the pain.
