depressed

Why is the husband and wife so depressed? The husband is depressed and the wife is a bit blue. WHAT SHOULD I DO! I have tried praising them and everything, please help me.

A couple of things to consider is whether they want kids, and if they spend any time together:

If they don't have any children yet, and they want kids, they might be blue about that.

If it's togetherness they need, try having them watch some movies together, and that should also help increase their happiness.

thanks
