Grammer Police

I don't want anyone to think I am the grammar police, but you need to know that bad grammar makes you sound stupid.
Many people have started saying, "I feel badly." This is probably wrong, unless they have some anti-social mental disorder. The difference is like saying, "I smell badly." when you have a cold, and saying, "I smell bad." when you are sweaty. "Badly" is an adverb describing "feel" to say you don't have trouble feeling. What people mean is that they are feeling, and what they feel is "bad".
Then there are the misspelled words, or rather correctly spelled homonyms. Spell Check catches the spelling, but not if it is the wrong word. The common culprits:
Sight, site
I often see web sight. You might see a sight on a site. A sight is something seen, but the right term is "web site" for a place on the web.
There, they're, their
There is not here. (Not hear. They're loud over there. You can hear them over here.)
They're is a contraction for "they are".
Their is not yours. It belongs to them. If we had a consistent, logical language, it would be they's. In common "black english" or Ebonics, they use they. "They music ain't loud. I cain't hear it over here."
To, too, two
Two is 2
too is also
to is the other one. It is one of those words we use that is very hard to define. It is used in helping verbs. Just learn the other two, and that one will make sense too.
I am not being the grammar police. I just want you to know that some people notice this, and they can't help feeling that you are less intelligent when you make these simple mistakes.
