Giving something valuable does not require making the receiver feel small.

It is possible to give a lot and take more than you gave. The tone that makes clear what a sacrifice it was, the reference to it later, the slight air of rescue. What the person keeps from the exchange is the smallness, not the gift.

Give as though it were ordinary, because to you it usually is. No emphasis on the cost, no recounting. That plainness is what allows someone to accept something significant without paying for it in self-respect.
