Then you must teach my daughter this same lesson. How to lose your innocence but not your hope. How to laugh forever.

The speaker frames “innocence” not as something that can be preserved intact, but as something inevitably altered by experience—especially painful experience. The plea is for a different kind of inheritance: not naïveté, but resilience. “Hope” and the ability to “laugh forever” suggest emotional survival and continuity across generations, implying that a parent’s hard-won wisdom should become a daughter’s protective knowledge. The line balances loss with endurance: one can be disillusioned without becoming cynical, and one can carry trauma without surrendering joy. It also underscores a central Tan concern: what mothers try to transmit is often less about facts than about strategies for living.
