i noticed that so many people (on blogs or in letters or whatever) write YOUR when it should be YOU'RE. and it bothers me. i don't know why, maybe its pointless cause who cares if someone write your or you're. well i do..
i'm not saying i'm a freaking genius and i never spell anything wrong. i come close though. and i do understand the difference between YOUR and YOU'RE and how to use it in a sentence.

there is a replacement test that will tell you for certain which word will fit. read your sentence with "you are" in place of the "your/you're," intended. if it makes sense, then "you're" would be right. if not, then "your" would fit. you could also replace "your" with "my" in the sentence. if it fits, then use "your."

i just thought i should share this with you. for a better world.
