How vocal are you during games? I am not...at least not when in attendance. Great plays, TD's, most likely I'll say, "YES"... and that's about it. I'm instantly into the next play.
Watching on TV I'm a lot more vocal. And yes, lot of negativity. On TD's I'm probably more likely to utter a "don't get cocky" than a "hurrah". Celebrations, for the most part, I reserve until the final gun after a win. I've do celebrate occasionally... I went nuts on Waddy's TD.
Basically I'm pretty laid back.... other than body language and the tangible stress on my face. I talk very little to others during games. Don't want to be talked to either.

Commercial breaks, TO's, halftimes, I'm nearly catatonic with anxiety waiting for the next play.
I'm different if on the GTF.... where I try to express what I'm thinking about plays, the situation, players, but I NEVER get it exactly right.
In summary... I'm the WORST person in the world to watch a game with. - JamesJM
