Mid thirties, early forties, is a time for deep philosophy, especially for a woman. You are finally coming to terms with husbands/boyfriends, after the umpteenth fresh start (or not). Your reservoir of patience to adjust with things becomes a ghost of its former self. And with that comes a defiance of the dissenters. This is who I am, you say to yourself.
In your new role, you will soon discover, that your strongest allies are that handful (read one or two or three) girl friends who have stuck with you through the thick and thin over the years (over breakups, new romances, old escapades). They are this incredible audience that compliment you on your sexy new dress (despite the love handles), ask for pictures of your current crushes (and equanimously enquire after your husband's cholesterol levels), boost you up when you have unsavory inlaws on your hands (with special tricks she has evolved to handle her lot) and in general let you hang your hair loose (even if that is growing scant).
Count your blessings lady, because, this, is as good as it gets, ever.
