It's difficult enough shopping for your own college kid or 20something. Try shopping for his or her beau. It's like traipsing across a gift minefield. Who knew gifts had subtexts? Well, we all knew that, actually. But here are some ideas for wonderful gifts - backgammon boards, Blue Bottle coffee, a little touch of cashmere and a hilarious, quirky book about a katana-wielding sushi chef - that will delight any 20something, even the young man or woman you really don't know very well, but who may eventually become a member of your family. Merry merry!
