This is by far, one of my largest pet peeves. It might even piss me off more than people walking into the bathroom barefoot.
It irritates the hell out of me when people show up late to class. I understand if you're working, I totally understand if you got caught in traffic, what I CAN NOT stand is those lazy and disrepsectful people that will stand on the sidelines and outside the front door while we work out and then come into the class, put on their gi and expect to roll with me after I'm dripping sweat, tired as fuck and ready to collapse.
It is disrespectful on a number of levels. Openly being late and doing things half assed shows how much worth you apply to your instructors time, your instructors teaching and your classmates. If you want to have a social hour how about you take that 130 dollars a month that you spend in BJJ and go to the local sports bar and buy a couple of beers three or four times a week.
While I'm on this soap box, it pisses me off that I'm consistantly the only person above the rank of purple that show's up for the warm up and stretch, then I'm the only brown belt who does the shrimping drills, or during the technical portion of the class I'm the only person trying to rep things out more than 3 times.
The lazy SOB's that want to rep it out 6 times and stop are not only hurting themselves but they are hurting me. It's gotten so bad that I have to grab a fucking white or blue belt so that I can get my reps in, the browns and blacks just seriously dont give two shits.
Show some respect to your instructor, come to class on time (if allowable), and train with the energy that you have. If you want to go slow, go slow, but dont stand on the sidelines and talk with your other groupie friends during practice time...or heaven forbid, during actual instruction.
that's not my 2 cents...thats really only about half of a cent.
