Hhmmm...least favorite chore...mine would have to be dusting. That was "my job" when I was a kid - and we had so may knick knacks to have to dust, and we live on a dirt road, so it's a never ending job!
Ironing. I simply don't do it anymore unless I'm sewing. When I was a teenager I had to iron my own clothes. When I became good at it my mom would make me iron my dads clothes too before I could get gas money to cruise the Sonic every weekend. We (my sister and I) also had to make our bed, clean the bathroom behind ourselves and dust and vacuum the living room before school in the mornings. My mom worked and raised 3 kids on her own most of the week while dad was out of town working.
