Cranky tonight. Working on CAD drawings. Pain in the ass trying to make the weird cuts fit and show it on the 2d drawings, frustrating. Sadie got into the kitchen garbage while I was gone. Partly my fault for leaving it out, but she knows it's bad. So she got shunned. Then putting out food for everybody, including food for Sadie, and not five minutes later she set off the dog trap at the cat food feeder. She's just being bad tonight, and I don't know why-- but it does not improve my mood.
