On the other hand, the answer to the question, "How many more teapots/cups does a woman need to serve her assortment of herbal teas?" might also lie on how the motivation that distinguishes between internal and external rewards is intrinsically embedded in the person's psyche.
Like asking a woman, "Why do you need all those shoes?"
And, she gave you a cold stare, because she was planning to go for more shoe shopping.
Or asking a woman, "Is that a new dress?"
And she replies to you, “No, I got it a year ago. I just put it on now.”
I hope you got my point.
Just be nice and complement her.
No, you don't have to mean it.
Just say it and it might eventually grow on you.
Sometimes, some of us women buy things out of sheer want and totally for unrelated reasons like the teapots, teacups and the sets on the display.
But in all seriousness, when you own a few more teapots, it makes it easier to serve different type of teas at the same time.
After all when it comes to herbal teas, I like to think that there is a mystic opulence in serving and enjoying it in the company of family and friends, or to sit down after supper with a good book/kindle and a cup of steaming-hot herbal tea.
