Don't forget your and you're

Trick for there, their, and they're:
There - t here - here - the location of something
Their - t heir - heir - the owner of something
And they're - they(a)re

I'm normally pretty good at it, it just kinda messes with me when someone says over their or that's they're power.

Yeah

That's not you're problem

no that's it's brother

its not, the that's is proper, but the it's isn't.

exactly, that's why that's it's brother is improper. Expand it and you get that is it is brother instead of the intended that is its brother, because we don't know whose brother it is.

Their always wrong :(
