The incorrect usage of the pronoun "I" gives me shivers up my spine.

For me it's the constant and insistent English misuse of the word "yourself". I don't know how many times people have said "Oh, I wanted to talk to yourself about that." or "That would be important to yourself." I feel like asking "Which of my selves?" What the f*ck is wrong with "you"? Not enough syllables or summat?
