Taking advantage of your opponent's blunders

This was a 5 min blitz game, in which I was able to find and utilize some simple tactics to punish my opponent's blunders. I must admit, I wasn't really interested in doing too much analysis in this game (that's why the time paramters were only 5 min/game -- and I was at work waiting for my ride), and after commiting a blunder of my own, I was delighted to see my opponent's mistake, which put me back in the game.
