Do You Tell Them?

You're out shopping with a friend, and just as she holds up the most adorable dress, gleaming with joy because they actually have it in her size, you notice something small and green lodged between her pearly whites.
"Don't you love this?" she says, unaware of the ugly little morsel marring her smile.
"Uh." You're eyes are fixed on the green thing. "What?"

Do you tell her?
For me, the answer is of course! You're her friend, right? That one's easy.
Let's try this: You're meeting a new co-worker for the first time, and upon introduction you notice his fly is down. That one's a bit tougher.


My situation is a little different, and hardly embarrassing at all. Just odd.
So I'm at the grocery store the other day, wandering through the place and filling my cart with everything on my list. Same old, same old.
But then I get to the front, ready to pay, and realize that my backpack has been wide open the entire time.
I don't mean that it was simply unzipped a little, giving a limited view of its contents. I mean it was way open; stuff was on the verge of tumbling out. I'm surprised I didn't loose the novel I had stashed in there along the way. (Luckily my wallet was in a different compartment.)
Now what makes this situation odd, is that I talked to a couple of people in the store. A few workers who politely asked me if I was finding everything okay. (Yeah, like the stuff that's flying out of my open backpack as I walk down the aisle?)
But one woman stood out to me the most. We talked for a moment about the produce. She was at my side with surely a perfect view of my wide open, just-about-to-dump-everything-out backpack. And she didn't say a thing. Sure, she seemed a bit shy, but still. I just can't imagine not saying, "Hey, your bag's open. Looks like you're about to lose a few things there." Right? (BTW, as far as I know, I didn't lose anything.)


So tell me what you think.  Have you had a moment where someone spoke up to save you a bit of embarrassment? Or a time where you wished somebody would have?

Are you the type to tell people when you notice something you'd want to know about?
Or let them discover it on their own?
Confess it here and now; I promise to still love you.
