I hate when people tell you how to play. Another thing I hate is when people who don't play guitar try to tell you about guitar. One time this guy I work with was like "So, do you play any instruments?"
"Uh, yeah...guitar."
"Cool."
"Uh.....do you play anything?"
"No. I was gonna play guitar once, but I quit after one lesson."
"Oh, I see."
"Can you play 'the Purple Haze'?"
"Um......................yes."
"Yeah, that's hard to play."

WTF?!?!?!
