Know-It-Alls

Is there anything more annoying than someone who thinks they know everything? I have to listen to two of this type of people every time i go to English class. I'm so sick of listening to these people taking up my valuable time so they can make themselves look better for the teacher. The best part of this is that neitehr of them actually know what they're talking about! This type of person doesn't exist only within the walls of my English classroom though. I go to PE 7th period only to come into contact with more people of this type. A girl, who by the way has gotten cut form every team she has had to try out for, is telling me how I'm supposed to set a volleyball. Wait a minute... Who was the one who used to play volleyball? ANd for that matter who is the one who was just told she had good form by someone who is currently playing volleyball? i'm so sick fo rtheis kind of person talking about how they know how to do things so much better than me when in reality they can't. I don't mind listening to someone who actually knows what they're talking about, but for those of you who dont... SHUT UP!!!
