I always try and grab at least a little something for Charlie too when I am out. He also gets excited when I bring home bags thinking there must be a goodie for him somewhere in that bag too. lol I almost feel bad when there isn't.
They are as bad as kids, aren't they?!?! lol
And when I don't, I just pretend I did by giving a piece of a cracker or something I bought from the grocery store, for example.
