What gift do you get your mate when you are afraid that no matter what you give her, she will hate it?
As long as whatever you give your partner, you give the story behind the gift, the chances of her hating it will decrease dramatically. True giving has time, energy, and thought attached to it. Rather than simply handing the gift and waiting for a reaction, as she is opening it, tell her how you found it, why you thought of that particular gift, and the process it took to get it from its source into her hands. No matter what material gift you give, it is the story behind it that is the true gift.
