I freely admit I'm an awful typer. I try to catch my mistakes (not always very good at doing so though )

Anyway, my biggest pet peeve that I've seen many people - both young and old do - is using "of" instead of "have"

For instance: I should have gone to the park

Someone would say: I should of gone to the park.

I know they are thinking what they hear. We constantly murder english in our speach. What we are saying is "should've" which is a contraction of "should have".

"Of" is a preposition. "Have" is a verb. Don't mix them up!

Tomorrow is a big one I see. Someone wrote "tomarra" the other day about a dozen times in a handful of posts and I wants to scream. One mispelling is understandable (and if I'm typing even expected ) but spelling the same word wrong the same way time after time?
