Feeling snarky

I went to an advanced kickboxing class last night, taught by Olga (she scares me). There were a lot of buffed up guys in the class, a couple of fit looking chics, a soccer mom and me, the "fat chick". Olga comes by and asks me if I am coming back to her Sets and Reps class on Thursday. I say no, I am competing in Warrior Dash on Saturday and will need the use of my arms. Last time I took her class it was an effort to life my arms to even type for two days.
After class as we are gathering up our stuff to leave, she says to me. Good luck on Saturday, then turns to the class and says, she is competing in Warrior Dash this weekend.
Two of the younger buff guys look at me, puff out their chests and say "Uh yea, I was gonna do that but I had this thing." "Oh yea me too, I was gonna do it too but then I had to do this other thing"

It's snarky for sure, but a part of me thought, Uh huh, keep telling yourself that. And while you sit on the couch on Saturday scratching your balls, watching football, the fat chick is getting muddy and jumping over fire.

That is all.
