Maybe one of her kids has a pen pal down there.

The two were pen pals and decided to start the project.

"I have pen pals all over the country now," he said of the children who wrote him.

That explains why some of my best friends are little more than pen pals.

And that weird phone call from her pen pal, David.

"But I like the idea of remaining pen pals with the people who come here for a visit."

At last, they arrange to meet their pen pals in person.

Far too good for the likes of it she loved having a friend, a pen pal.

And try to find a pen pal for your child from that country.

"The best we could do then was to be pen pals," he said.
