011. NEVER interchange your and you're, its and it's, their and they're, who's and whose, all right and alright AND farther and further.  I mean it. Not only will you get your readers confused, your story will go down the drain.

DEFINITION
your- OWNERSHIP
you're- YOU ARE
its- OWNERSHIP
it's- IT IS
their- OWNERSHIP
they're- THEY ARE
who's- WHO IS
whose- OWNERSHIP OF WHO OR WHICH
all right- SATISFACTORY
alright- PLEASANT
farther- DISTANCE
further- QUANTITY WORD

ALTHOUGH ALL RIGHT AND ALRIGHT MEANS ALMOST THE SAME, ALL RIGHT IS STILL BETTER THAN USING ALRIGHT SINCE ALRIGHT IS NOT YET APPROVED TO CHANGE ALL RIGHT.
