It is. It's very bad. Cause, dammit, f(gf'(x)g') is not like gxg', no matter how hard I try to make it be!

I'm all tense and pissy.

With the weight I lost I'm now able to wear my grandfather's cashmere coat. It's beautiful and finely made (likely a hand me-down from a parishioner) and I needed to have the lining patched because it was haniging down in the back

they wanted to replace it, I said, no patch it... I knew the lining was nicer quality than anything they'd have and I wanted to preserve the labels and stuff

I have it back. one of the labels is missing [link] like that, said 'cashmere' and now I'm all pissy and feeling like I should have researched first (turns out Hickey Freeman IS quite nice and still exists)

So, tomorrow I'll go to the drycleaner but I'm sure the label was thrown out yesterday. And I"m cranky and antsy about this, unreasonably stressed.

Oh, and yeah, I'm completly aware that I'm just missing the hell out of my grandfather and projecting it onto his coat but that doesn't seem to be relieving the pissy stressy at all.

I've gotten myself in a bind over showing that the inner automorphisms of G form a normal subgroup of the group of automorphisms of G under function composition.

I can't even read that whole sentence.

It helps if the words "form a normal subgroup" and "under function composition" form actual phrases in your mind. Without that kind of context, it's just a string of words skulking around with Intent to Have Too Many Letters.

Trudy, I do this too. I'm sorry about the coat - hopefully they will help you tomorrow.

Also automorphisms, which is where my brain gets stuck.

I'm feeling crappy tonight. I seem to have forgotten how to live nicely with other people in the last year. Also, my husband deals with stress by sleeping, so he and Ellie have both been asleep for the last hour and a half. Which is fine for them except that I am alone, again, like I have been all day.

They'll just make a face at me, they thought I was nuts to keep the lining.

Grrrrrrr.

I suppose its possible its in a wastebasket. But they'll still make a face at me.

I'm also feeling like a hay-seed. I don't know a fine coat when I see one, apparently.

Well, I knew it was nice, I just didn't know what to do with that fact.

What I particularly like is that there are automorphisms, isomorphisms, and homomorphisms, and they all mean different things and I'm supposed to keep them separate. Except don't they all mean "same/equal shape"? I mean, I do know what they mean, but... argh.
