Basically...

That awkward moment when you realize it's not a typo, you're just really bad at grammar.

Every time i see a word too much and it dont even look like a real thing any more

i once read a book written by a well known author and there were 2 grammar errors! this irks me but i love the story so much so i have to face the grammar errors everyday! :(

It makes me shiver every time I see a grammatical error

I've got the lead role in my school musical and in in my libretto there are about three or for spelling mistakes. I cringe every time I read them :P

When I see that a period isn't there or whatever I write it in
