I'm now slightly concerned that DH never displayed any anxiety at the thought of me going to meet a bunch of strangers off the interweb.
Indeed, the last time I went to MN meet-up (and dangled a teeny tiny Annie from my giant fingers) my karate instructor showed much more interest, even to the point of threatening to come and 'check you all out' whilst on duty (he's also a Police Officer in Lunnon Town somewhere).
I dissuaded him from such a ridiculous plan by hitting him very very hard and wrastling him to the ground.
(Actually that's not quite true- he did the hitting etc and then I told him we'd just be talking about PERIODS and WOMENS' THINGS and he came over all wussy and started making 'bleugh' noises and desisted.)
DH, on the other hand, just said 'Oh ok.'
