Saying that he doesnt want to let the perfect opportunity pass him by, local artist Brian Danforth told reporters Tuesday that he makes a point to always carry a sketchbook around with him in case he feels like making a stranger uncomfortable. You never know when youll catch a glimpse of some random person and feel that sudden urge to sketch them without their permission as they fidget under your gaze, said Danforth, who noted that theres nothing worse than coming across an interesting and easily unnerved subject on the subway whom youd love to stare at intently from three feet away for several stops only to realize you dont have your sketchbook with you. A few weeks ago, I was sitting across from this great older gentleman at the coffee shop, but I had forgotten my pad at home and ended up wasting a ton of time trying to find a piece of paper before I finally just grabbed a napkin. But by that time, I barely even had a chance to make the guy feel completely self-conscious by darting my eyes back and forth between him and my pencil drawing before he got up and left. I wont make that mistake again. At press time, Danforth was switching seats on the 7 train to get a better angle on a passenger who had unfolded a newspaper in an effort to block his view.
