Character shows when we do the right thing even if no one sees us. Or something like that.
What I mean by that is, you should be getting sober for yourself, not for your child or your husband. If you are, then you will stay sober even when they aren't around. You might be able to fool them, but you cannot fool youself. They may not know you drink, but you will know. How badly do you want to live a sober life? That's the question you must answer.
