Libido will have out. You don't need to know what women taste like to know what women are like. Those who make the aberrant lifestyle choice of committing to one sexual partner for life should not be discriminated against. [Savage Love]

What the sell-by date really means. [Hints from Heloise]

Think of your morning Metro ride as a chance to train your child to be a tiny, sophisticated commuter. If your physical repulsion matters less to your husband than his wad of chew, he has a serious problem. Defriend your friend who live-blogged her traumatic miscarriage. Gum-chewing and teeth-grinding are equally annoying habits. Don't allow your forgetful sister-in-law's son's special sporting event derail your daughter's baptism. Refuse to take paid leave to attend a strange co-worker's retirement party. Track down your new neighbors and arrange a play date with their daughters before offering to swap the girls' plastic bags with your discarded backpacks. Deal with co-workers who carry on awkward conversations while urinating by responding in a monosylabic clip. You and your children are not required to attend the funeral of your husband's father, provided he never liked you. In order to salvage your relationship with your son, get over your homophobia. Send a personalized gift to the marrying couple who requested cash. Intervene before your mother kills someone. Informing your friends of your daughter's music scholarship does not constitute bragging.  [Dear Prudence]

Don't break it off with your military boyfriend of four months because you don't want to end up an Army wife. Apologize to your son for rejecting his engagement to a woman you suspect has a religious aversion to premarital sex. Break up with your retired millionaire friend because you dislike her, not because it's "unethical" to continue the relationship. You can accept an apology without staying friends. [Carolyn Hax]

Understand whether your girlfriend rejects the idea of having biological children because she is afraid of giving birth or simply doesn't want to dip into your gene pool before you end the relationship. Charge your child rent and return it when they move out. Stop your son from verbally abusing your mother and stealing all of her money. If you gifted your neighbors two excellent bottles of pinot noir that can be served with anything, then threw a fit when they stashed the bottles and served a cheaper wine instead, perhaps you were served the wine you deserved. Do not assume marital status from the style of a woman's clothing. [Ask Amy]
