Instead of buying your best friend another cable-knit sweater this Christmas, take the money you’d spend and donate it to a good cause (not her closet) in her name. Not sure which charity she’d pick? Buy her a gift certificate from JustGive (www.justgive.org), where she can choose from more than a million charitable organizations. Now you can both feel the warm holiday fuzzies— just not the ones that come from a woolen sweater.
