Where I contradict myself.

I have a favourite line that I like to throw at my friends who express their regret/guilt/angst over certain situations in their lives. And you all know who you are.

Guilt is a useless emotion.

And it is.

Except when your five year old comes to you at 3 in the afternoon complaining of a headache, and telling you that she needs to drink some water, and you realize you haven't given her any all day.

And then she proceeds to guzzle down three cups.
