['My son sits around all weekend and eats everything.', 'Tell him to get out and do something! That must be frustrating.', 'Well, he pays rent but he definitely uses up more resources than he pays for.']

I go grocery shopping on Saturday morning, and my adult son has the weekend off and he proceeds to sit around all weekend eating all the food with zero self control.
