bad Bad BAD graduate student

OK, I just spent 30 minutes with the Tasmanian Devil Undergrad (the one that leaves a wake of destruction where ever he goes) arguing about affinity purifications. He has NO experience in the lab. He has little experience in coupling chemistry. He does not believe in enzymes. He does not know the pKa of water. And yet, he argues with me about everything.
I know my stuff. I know how to do affinity purification. I have been doing affinity purification in some form or another for close to 12 years. I am good at it. I also know my way around coupling chemistry, since, you know, I was a tech doing synthesis for a couple of years before grad school. I also know my way around some enzymes since I have, you know, an B.S. in biochemistry from a swanky school and 5.5 years completed in my quest for the Ph.D. in biophysics from a swanky biochemistry graduate program and the last three of those years have been spent in the lab of a very reputable and highly esteemed enzymologist. AND, I know the pKa of WATER!!!
And yet he argues. And argues. And asks hazy, infuriatingly vague questions.
And my group meeting for the Stoopid group is not done yet. I don't even know what I want to talk about yet.

Fuck.
