### Crafty me & a computer-generated passive aggressive note

Firstly, I've had some data integrity trouble with the photos of the one thing I ever knitted, a coat for my first kid. So the bottoms of these photos are missing. Sorry. But here's my daughter pretending to be a ghost, and then peek-a-booing. This coat took a very long time to knit, because I had never knit anything before. It was arguably an unsuitable project for a beginner. Still, I enjoyed doing it & I love these photos.

Also, while I'm at it, I'll post the best painting I've ever done. I'm not much of an artist; I'm the artistic dunce of the family. But a couple fo days ago I got roped into joining in when my concubine & our daughters were painting, with this result:

Lastly, a passive-aggressive reply I got from the computer algebra package Mathematica a couple of days ago. I'm not sending this to Kerry, because I doubt it will be everyone's kind of thing, but maybe someone here will see the funny side. I had a system of equations I wanted to solve. These equations involved complex variables and their conjugates (that is, variables from the complex plane and their mirror images reflected through the real axis). I entered my equations into Mathematica which, like Maple (which I had tried first), was unable to solve them. But whereas Maple had just said "sorry, I can't solve your equations" or something like that, Mathematica tried to blame me:What I'd like is to know what all the solutions are, but I'll have to live on in ignorance. I did manage to find a couple of solutions by hand---though evidently, whatever I was doing, it wasn't really "algebra".
