Feeling Crummy

As a mom sometimes I just get to the point, where I can't deal with my kids any more. All the stuff they do or don't do builds up till I want to explode. I am so tired of being the bad guy. I am the bad guy with Bubba because I want his room clean every night before he goes to bed, I am the bad guy with Josh because I don't drop everything when he wants me to come and get him out of school, or when he changes plans and instead of walking to football right after school, he comes home and wants a ride. I don't mind that he wanted a ride, but I had to wait for my girls to get home, and then a lady was coming to get a kitty, it's not like I could have just left. I am the bad guy when they want to play after school, but I say no because their chores aren't done, and they have homework. I am the bad guy because we have to go clean AVU.
I had had it yesterday. So after we were done cleaning AVU Josh took my car with all the kids and I took his. He had a talk with all of them on the way home. I don't think they knew what they were in for, neither did I . But after they got home and I saw tears in all of their eyes I felt like the worst person ever. Not what I wanted. I don't like to see my kids cry.
I know ever once in a while they need a good firm talking too, but it sure makes you feel bad.
