*shakes head sympathically at Dotsie* Luckily I'm too old now to get that any more (although technically I could still reproduce). I once said 'No I'm not - but if I did I'd make them blow their noses once in a while'

Luckily she was a good enough friend to laugh it off...
Seriously the 'I can't have kids' one is the clincher of course, but it's sometimes the hardest to say, even if it's true, because
you feel bad admitting to it in the first place and also because you feel bad when the asker gets embarassed or sad for saying it at all and
then you get the pitying looks as well... even though as you say it's none of their business and why should you be made to feel so awkward.
And mums are just too much, especially if they team up

I really don't know why people even ask the question - I never have as I think it's a really intrusive thing to do.
As for flaming can-openers!

I'm left-handed and my housemate's right and it just infuriating how often the ones we managed to find that 'go both ways' never seem to last long and as you say the electric type ones are temperamental but it's not just openers - peelers are horrible (although Tesco does do a 2-way hand held that
doesn't make you feel like your fingers are being slowly re-sculpted and feels reasonably comfortable to use) and knives!

Luckily Pete doesn't use them too much but we have got a couple of 'hers only' ones so he doesn't skew them and make it impossible for me to cut up meat effectively (you wear the edge on one side so if you both use the blade then it's not as sharp...
