We invest less in our friendships and expect more of friends than any other relationship. We spend days working out where to book for a romantic dinner, weeks wondering how to celebrate a partner or parent's birthday, and seconds forgetting a friend's important anniversary.
Every friendship goes through ups and downs. Dysfunctional patterns set in; external situations cause internal friction; you grow apart and then bounce back together.
Contrary to popular mythology, the best and most durable relationships are based not on vulnerability or passion but on a conjugation of positive attributes, a meeting of mind, body and soul that is all the more powerful as it is not weighed down with neediness and unreasonable expectation.
Sustaining true friendship is a lot more challenging than we give it credit for.
Only those with skin as thick as elephant hide can hope to sail through their teens unscathed by self-doubt and bouts of depression.
The point of the feminist movement wasn't simply to set our underwear on fire and muscle into small spaces in the male-dominated workplace, but to create a world where the contribution of both sexes was equally valued and no one's worth was judged on their take-home salary.
When I last looked, there weren't queues of eager guys under 40 hanging outside single ladies' doors begging them to give up work and have their babies. It takes two to tango and the same number, without medical help, to make a child.
For many young women, the dream of independence and a home of their own is a tantalising goal, while a lifetime devoted solely to catering for another person's needs would be hard to countenance.
Placing 'amicable' and 'separation' together creates an oxymoron - we don't usually decide to end a partnership until the very sight of our soon-to-be ex fills us with disgust, misery, agony or a combination of all three.
Often, those who bruise easily spend too much time thinking about themselves. I'd go so far as to say that oversensitivity is a privilege of the underoccupied. The majority of people don't have the time to lavish care on emotional wounds - they're too busy getting on with living.
While the male eye zooms in on a particular element to the exclusion of all else, a woman's gaze flickers from one tedious task to the next, to the point where we can't distinguish between the importance of mopping the kitchen floor and achieving world peace.
Joy acts like a trampoline, everything that touches it bouncing right back off it.
Ageing is one of those battles you're not going to win. I'll try to look as good as I can as long as I can. I don't think I'll do cosmetic surgery because I'm a wimp.
Of course, I'd like to earn Jonathan Ross's money, but I don't have sleepless nights wondering when someone's going to knock on my door with sacks of cash.
In romance, we feel the need to zoom in and expound on our partner's foibles in intimate detail; in friendship, we tend to do the opposite, avoiding confrontation through fear, lethargy or both.
