It really is.
There is nothing fake about them. You can see that George W. and Laura really love, respect and admire one another.
They're just very comfortable with each other and it shows in this picture. It's a few years old, but it's one of my favorites.
what I get a kick out of is when GW is speaking and Laura is smiling from ear to ear. She knows, as do we, he butchers the Queen's english, gets a kick out of it, and loves him all the more. It's written all over her face.
