Your first summer job will show you who in your family has been tired for years without mentioning it.

Four weeks of real shifts teaches you something nobody could have told you. You come home with your feet hurting and your head empty, and then you look at the person who has done that for twenty years and also cooked dinner, and the arithmetic changes.

Say the thing out loud to whoever it is, this summer, while you can still feel your own shift in your legs. Keep it plain and specific about what you noticed. Then take one job off their hands on your day off, not as a gesture, just as the dinner that got made.
