Can barely keep my eyes open. Once again, I reached home at 10 today, without eating dinner. It's yet another long day in lab...

And can you believe it, the AIR TANK IS EMPTY AGAIN!!! Because my lab mate has been running hundreds of samples these few days. So I can't do my flame again...

Got to keep awake. I need to send my group member my powerpoint slides by tonight. Which I only started doing last night and am currently still at introduction. Sigh.
