Do you ever have a tough time remembering when to use Whose or Who's? It happens to the best of us. You are typing a message or writing a note and suddenly everything you learned in school is gone. I blame those moments on having to get up at 4:30 a.m.; or I use the excuse that I haven't eaten so my brain has no fuel. Then I try to think of a different way to say whatever it is I'm trying to say without using the word that is suddenly causing me to waste a bunch of time and energy searching for the proper way. The answer is here at last. My sure-fire way to remember Whose or Who's.
