My twelve year old favors my husband’s side, appearance-wise, the long legs, straight back, and Brad-Pitt eyes, but she’s very much her own person. Confronted by one of her unique inclinations, my husband and I will sometimes marvel, “Who’d she get that from?” In one respect, however, she’s all mine: She doesn’t part with stuff, at least not easily. Her messy bedroom pains my husband, the neatest person I know, but she can’t seem to toss, donate, or recycle much of anything. “It’s too special,” she says. (Our ten year old couldn’t be more different. Case in point: He used to tidy his kindergarten teacher’s desk for her during recess. For fun.)
