I know I can't be alone in this, but it completely drives me nuts to see there, their and they're used incorrectly!
A quick lesson:
There is a place, you can tell because it has HERE in it, also a place.
Their... means it belongs to someone, you can tell because it has HEIR in it, a someone.
They're... is a short cut for "They Are". So, if the sentence would still make sense if you switched it to "they are", then that's the right one to use.
Board is a noun, bored is an adjective which describes a noun. So if you are board, there's a problem!
Two is a number.
Too means also, if you could switch out also for your too, then it's the right one.
To, use this if it's not one of the others.
I don't claim to be perfect, in fact I'd like to be educated on one that doesn't come easily to me.
Buyer's Agent, is this right? Is there a time when it should be just buyers agent?
Any others that drive you nuts? Please feel free to add on to this lesson.
