I don't want to start a discussion
I'm just putting this here for anyone interested in seeing the difference so their messages are clearer to read.
Your - Belongs to you
Example: Your gear
You're - Short for 'You are'
Example: You're right
There - Referring to a place
Example: Lets go over there
Their - Possession
Example: Don't touch their RIF
They're - Short for 'They are'
Example: They're going to be surrounded
Hope this helps clear things up a bit.
