Ross Gellar from “Friends” had his faults, but I have to agree with his grammar. I see “you’re” and “your” used incorrectly all the time, and sometimes, I feel like saying exactly what he said to Rachel in this clip.

My best tip: if you are one to incorrectly switch up the two, say it out loud when you’re writing it. “You’re” is a contraction for “you are,” so if “you are” doesn’t fit in your sentence, it’s “your,” which is possessive.

Example:
You are welcome. = You’re welcome.
It’s your call. = It’s your call. Because “it’s you are call” clearly sounds off.

You’re welcome.
Your attention is appreciated!

Being a “Friends” fan, Tiffannie Bond, PR director and company photographer, thought the 25th anniversary of the start of the show would be a good time for a grammar lesson. If you’d like to help her put together her “Friends” LEGO set, let her know.
