Strider the Kid and Strider the Dog

My grandson's given name is Strider. And, yes, like his mother's name, it's also from "The Lord of the Rings," though she didn't choose it. Strider's father chose it, from the first "grown up" book he ever read.

It's a pity my former son-in-law didn't learn a few other things from that book, like how to honor his promises and fulfill his obligations, but the sad fact is that, when Strider was two, his father walked out on him and his mother, leaving them to fend for themselves.

(With a lot of help from his family, who have always treated Arwen as though she were their sister/daughter, and for which we are all infinitely grateful)

So, fast forward three years to an old friend joining a newly formed amateur baseball team and taking his wife and kids to their first game. The kids make friends with another player's border collie and, naturally, asking the dog's name. When Paul, the owner, tells them "Strider" (yes, also from "The Lord of the Rings") the two girls say something like "We have a friend named 'Strider' and he's coming to stay with us. And he'll want to meet your dog."

Fast forward another three years, when my daughter's family includes Paul, Strider the Kid and Strider the Dog. Neither Strider answers to a summons for the other and I haven't the faintest idea how they do it.
