A lot of what your parents gave up never got mentioned. Ask them sometime.

Sacrifice is usually kept quiet, partly out of pride and partly to avoid handing a child a debt. There were plans shelved and jobs not taken, and none of it was mentioned because mentioning it would have made you responsible. The silence is a kindness that leaves you with an incomplete picture.

Ask once, gently, and not during an argument. What did you want to do that you did not do, and would you choose the same way again. Then just listen, since the point is understanding them rather than apologizing.
