Last Night's Randori

While my and Andy's attempts to get our roommate Beau involved in classes haven't met with the success we'd hoped, so far we're having a blast. Last night we briefly went over ko soto gari for about 10 minutes then almost an hour of ground randori. Andy's getting much better at his ground work and because of this I noticed after class that during class I was saying things like "That was great, but make a slight adjustment here. Oh and try this" and by the end of class I must've given him 50 things to work on. I need to remember to just pick one or two things and everything else will just naturally happen. When going over ko soto gari I noticed my ko soto gari was looking fairly well last night but when I made a comparison to hize garuma, I couldn't get the throw to work for me :) the lesson there is, when a throw is working for you one night, you stick with it and change it up the next night. I've been in correspondence with Pat hoping to get some pointers now that I more fully understand what he was telling me a few years ago. It's frustrating when you get advice but you can't act on that knowledge until a year or so later when you ACTUALLY understand it. I mean you understand what the sensei is telling you when he/she is saying it, but it's much farther down the road when you say "Eureka !" and have an epiphany of what they were really trying to convey. Anyone else have that happen to them? I want some stories!
