Whose vs. Who's

After writing a post over a week ago, I Googled whose vs. who's.  I think I learned something new or relearned something I forgot.

This post does a lovely job of clearing the confusion in my mind of when to use "whose" and when to use "who's."  I'm simplifying the difference to this:  whose always shows an element of possession.

Hope it helps you, too, although you probably already knew the difference between the two, didn't you?
