Keep cool, bro.
Even if such a question was posed to AI, it will throw up a FEW possibilities, even the one that you thought of, which is LOGICALLY correct.
Ultimately, it is about giving the answer that she DESIRES for.
And the method is to take time to PROBE her thru casual conversations on WHAT that is SHE desires FOR but unable to buy, even she should she be rich enough.
Good luck.
