Send her this link.....My lovely wife came home from the hairdresser, and all I said was, "You look nice."
She then proceeded to throw the contents of the house at me. Apparently it wasn't what she had asked for. Having learned my lesson, I now say something along the lines of "I like it if you like it", or even "Tell me what to say!"
It's only fair, because I reserve the right to throw things when I'm plumbing. Sometimes it helps.
