Feelings of guilt

At work I am notorious for coming in late. If I'm in by 9:30 my manager celebrates. Most people think that I probably wake up at 9am and hop in the car, but that's just not true! I would get up at 6:30 (ish), have a cup of coffee or five, then take the dogs to the park for their morning run around, come back home and have another cup of coffee, shower then finally head to work. But recently my company started offering a bus shuttle from the park and ride near my house to work. Since I drive my SUV 60 miles a day (both ways) and cross a bridge, I figure I'll be saving over $400 a month taking the shuttle 4 days a week (I can't take it 5 since one day Icon comes with me for class). BUT. The shuttle leaves at 7am, which means I get up at 5:45 and leave to catch it by at least 6:40, which doesn't leave me enough time to take the dogs to the park. The most they get now is a quickie walk around the block, which I only do because otherwise Polly refuses to pee for me. So they are gettin gway less exercise now. And then when I get home from work I always have the best intentions of taking them to the park, but I'm soooo exhausted I just don't have the energy so I end up playing with them in the back yard. Anyway, I really feel guilty about the lack of exercise they're getting. But I did take them to the park last weekend and the grass is so brown and dead I think it would be hard on their feet to run on it, so maybe it's for the best.... yeah. I'll just keep telling myself this :)
