Should I Worry about Weeding?

While mowing, I noticed just how badly the cotton needs weeding. Maryann and I planned to weed yesterday, but that fell through. She had too much too do before leaving for Dallas and I am too lazy to weed without her motivating camaraderie. Maybe we should just let the grass grow in and weedeat it as it gets too high. I know the grass will require more watering in order to keep the cotton healthy and growing at an appropriate rate. I also know weeding is fruitless. Weed today, weed tomorrow, it's never ending. I need someone to weigh in on this.
