Not always out of the mouths of babes: sometimes the truth comes out of my mouth, the truth that I needed to hear.
My younger son came up on the train this morning for a visit, and on the way home from the station we stopped to get sandwiches. As we were leaving the bakery I handed him the bag and said "Be my beast of burden!" He laughed and replied "I've been here less than an hour and you're already loading me down with stuff. And I shot back "Why do you suppose people have kids? Because they're tired of carrying around their own baggage!" And then we both laughed and I said that was probably the most profound thing I've said all week.
