I have given up waiting for certain people to turn up. I just tell them, in my brutally honest way, that if they are not there and have not called within 20 minutes of the arranged time, I will go without them, as my time is too precious to be wasted.
God, that sounds so bad when I see it in black and white!!!
Most of my friends don't have children though, and I feel that if I can maneovre a truculent toddler out of the door, with pushchair, nappybag and spare clothes, they can run a brush through their hair and find their damn purse!!
Lack of commitment to arrangements drives me nuts! People who don't have children do not understand the sheer effort you have put in to get to a certain place at a certain time, or how precious a night out is to you.
When you have managed to arrange a night out with the girls, when your bloke is at work, having wheedled your mum into babysitting, juggled the DD payments so you can afford it, booked a taxi home, managed to find and iron your only flattering top, applied makeup to your face for the first time since Christmas and rammed your protesting feet into high heels, the last, the very last thing you want is a phone call saying that said girly friend is a bit tired from work, and wants to go horse riding tomorrow, so thinks she'll have an early night.
Long sarcastic rant I know, but this exact thing has reduced me to tears on several occasions!
