Mini-rant

I was reading a blog this morning and saw the phrase "their responsible for it..."
Honestly don't they know the proper use of they're? If they had been in my classroom they would have to write this sentence five times.

They're going to put their apples over there.

If they did it again they would do it 10 times. The kids always said it was just easier to do what I wanted - and that was one of the things. Use their, there and they're correctly please.

The following is from Wikihow:

Use there when referring to a place, whether concrete ("over there by the building") or more abstract ("it must be difficult to live there").
There is an antique store on Camden Avenue.
The science textbooks are over there on the floor.
Use their to indicate possession. It is a possessive adjective and indicates that a particular noun belongs to them.
My friends have lost their tickets.
Their things were strewn about the office haphazardly.
Remember that they're is a contraction of the words they and are. It can never be used as a modifier, only as a subject (who or what does the action) and verb (the action itself).
Hurry up! They're closing the mall at 6 tonight!
I'm glad that they're so nice to new students here.
Test your usage. When you use any of these three words, get in the habit of asking yourself these questions:
If you wrote there, will the sentence still make sense if you replace it with here? If so, you're using it correctly.
If you chose their, will the sentence still make sense if you replace it with our? If so, you've chosen the correct word.
If you used they're, will the sentence still make sense if you replace it with they are? If so, you're on the right track!

See the mistake?
Recognize incorrect examples and learn from the mistakes. By looking over others' work with a critical eye, especially by offering proofreading or copyediting help, you can become more sensitized to correct usage and practice it yourself.

And just for a little over kill"

Their is a possessive pronoun. It always describes a noun.

Note the spelling of their. It comes from the word they, so the e comes before the i.

There is an adverb meaning "that location." It is sometimes used with the verb to be as an idiom. It is spelled like here which means "this location."

They're is a contraction of they are. Note the spelling: The a from are is replaced by an apostrophe.

Examples: Their dog has fleas. (possessive of they)

I put the collar right there. (that location)

There are five prime numbers less than ten.
(with to be)

They're 1, 2, 3, 5, and 7. (contraction of they are)

There now doesn't that make you feel better?
