So I didn't buy the portrait lens. Turns out I'm lazier than I thought, except for pictures!
Some growing pains advice, if you're looking to take pictures of someone interesting don't try to hide it. If they catch you introduce yourself and tell them what you're doing. If not, just run really fast.
Yesterday I ran into a guy who showed a bus ticket and said "this is where I am going," his ticket said "Newark." I responded to him "Oh, going to Jersey?" and he goes "no, I'm going to Newark."
I hope he made it home ok.
