Funny how improper use of punctuations can change the meaning of the sentence or phrase, isn't it?
That is why it is important to use the correct punctuations at the right place in a sentence. Here is one of the most common mistakes on Punctuations and Grammar:
* You're and Your
- Although they sound the same, you're and your are quite different on paper.
You're is a combination of the words you and are.
You're (You are) the funniest person I have ever known.
