that "small" annoyance

Have you ever had something you enjoyed doing nearly ruined by an annoying person? The drunk guy at the baseball game, the obnoxious laugher in the movie theater, the loud talker at the restaurant. Well, this week I have had that ongoing experience and I might be at my breaking point. None of us like awkward situations, and I, for one, am not a fan of confrontation, especially with strangers and near acquaintances, but I also dont want the one thing I do just for myself ruined by an overdo-er.
So my issue is this; I go to this really awesome gym, as some of you already know. And I love it. Everyone there is fun, and we have a good time, and its a very positive experience for the most part. Except for this ONE person, who I rarely have had to train with us as they are usually in a different class. This person is a "look at me" person. Loud, obnoxious, always correcting others without being asked, talking over the other trainers, and generally a pain in the ass. This person has the attitude that everyone should be doing prescribed WOD's, and if you don't, you aren't "in". Well this person has been in my class this week, and I'm beginning to dread my workouts. I am interrupted more times than I need to be, and their is tension in the air. I want to say, " Hey, PERSON, your form ain't so hot either. And I don't care to snatch 65lbs, nor do 100 burpees in a day, nor do I feel the need to compete against a white leader board." The spirit of Crossfit is to push yourself to do better than the last minute/workout/weight. Not to push others where you cant succeed.
SO I am sitting here, still in bed, pondering if I should go to class today and face this annoyance. I guess I can at the very least drive by and see who's in the gym. Ugh. Here goes...
