Household disasters

It started last night, when I went to take a shower - the shower is a mounted handheld, and it has become possessed (or the hose is all twisted) so the spray won't go straight ahead into the bathtub so you can stand under it, only up against the wall, or, even worse, rotating over the top of the shower and out into my room. But, OK, I can get over it, disasters that happen when you are naked without your glasses on are unusually bad...

Then this morning, I wanted to open the kitchen window, and the right hand blind, which always worked (unlike the left which does not) decided to not go up, and then after I got it to go up, would not go down ...

And the cat pulled down a vase of flowers including the water of course, and I almost spilled a container of veggies with peanut sauce that I intended to take to work to heat up and eat in pita bread for my lunch ...

I don't think any of these would bother me so much except I am planning a dinner, and I am superstitious enough to worry that if I can't make these everyday things work right, how will I do with a big event?
