Am I Being Unreasonable?

I wanted to buy some tights today for Eldest Baby Smat. They're for school, so have to be black. She's not especially careful, so they need to be at least 40 denier to minimise laddering. They need to be either ladies small, or childrens age 13-14.
So, off we go to Bluewater to the flagship M&S store. Big shop, rubbish weather, plenty of tights, yes? Well, actually no. Children's department have plenty of navy blue tights in all sizes, or black in age 5-6. Women's department has brown. In Large or Extra Large. Apparently there's "no call for plain black tights any more". Since when? We don't all have the legs for fishnets these days.
So, Am I Being Unreasonable? I don't think so.

(and if you know of anywhere which sells 40 denier black tights in Small, let me know please)

Look's like November's going to be busy

I've just taken on two new clients (well, both old clients really) for book-keeping and general financial stuff, as my wishlist of things I want has got longer and more expensive. But, one client needs six months of work done in one month (that would be November) and if Gordon listens to David then I'll have a night of weighing the Tory vote as well. So a 4am finish on the day of a general elction, which means missing 6 hours of sleep, which means another 12 hours is needed to catch up, which means I'll surface sometime in December, just in time to pick up on other client, all in the run-up to Christmas.
Eek.
