Gift giving can be tricky. And if you believe in the polarization of gender and biological determinism, be aware that you need to stick to highly feminine and masculine gifts that reinforce the belief in the segregation of women and men.
Red Envelope has a whole section of gifts for her, and for him. Subcategories for women (that are not included in the men’s section and vice versa) consist of “cooking and baking,” “flowers and plants,” and “gardening.” Subcategories for men include “sports” and “electronics and gadgets,” as well as “watches” (there’s a clear distinction between a watch and a piece of jewelry, right?) Some categories are similar, but assumed gender preferences are included. For example, for women there is a section called “for the home,” but for men this similar section is called “home & office.” For women, there is also a section titled “bar & wine”; the same section exists for men, with the addition of cigars. See, this is helpful because we would not want women smoking cigars in their offices and men to dirty their jewelry in the garden.
