I once was approached by a woman I'd never met, online or off, who asked if she could write a guest post for Grandma's Briefs. Other than a guest-post trading stint featured as part of a SITS activity, I had never published guest posts here. Funny thing was, I was swamped and in desperate need of help. So I said yes, Grandtravel was published, and a stranger named Mary had saved the day. End of story.

Or so I thought.

Not too long ago, I was contacted again by Mary, with an idea for another post, wondering if I might want to publish it. Again, she had come along at exactly the right time, exactly when I needed her. I published Grandparents can be fun AND consistent, and once more, Mary — now no longer a stranger — saved the day.

That's still not the end of the story, though.

The rest of the story is that the guest-post-writing stranger named Mary, the woman who saved my butt the day...twice...is this week's Grilled Grandma.

You've read her articles on grandparenting (and if not, go ahead, read them, then come back). Now it's time to read about her. Please give it up—meaning the clicks and the comments—for Grilled Grandma: Mary, an online angel who somehow magically knew I needed her, even before I knew that I did.

Now that, dear readers, is the end of the story. At least for now.

Call for guest posts: I'd like to throw a guest post or two into the mix during the time I'm away meeting my new grandson. If you would like to submit a 300- to 600-word post on any grandparenting topic (no ads or promotions, please), please e-mail it to me by Tuesday, June 14 for consideration and possible inclusion. Openings are limited, but I hope to fit in a few. Thank you!

Today's question:

When has a stranger made a difference in your life?
