I don't know that "sneaky" is something to look for in a mate, but David uses his sleuth skills for good, so I think it's okay.
I have mentioned before that he is a really good gift giver. Many times I have been surprised that he's remembered something from 6 months ago (or more) that I really liked. This time I was mystified as to how he knew that I liked this headboard for our guest room. Finally I got him to confess...I'd saved it in the Favorites on my iPad. He is a smart guy!
Henrietta and I love the new headboard! I think it looks really pretty in that room.
