What a great topic!
My kids have always had chores.... dishes, bathrooms, helping with dinner, lunches, laundry, general cleaning when I was a single working, homeschooling mom.
This became more difficult when we blended families as the practice was just a little different and I am still building my "roll" as a parent to my husbands children. It has been hard to expect my children to do these things, but not feel comfortable in expecting the same from the other half of children... we are working on that 
Right now the chores are
Boys (teenagers)
do their own laundry,
make their own snacks, breakfast, clean up after themselves,
clean their rooms (although I am lax on this as I don't really care if they make their beds and have spotless rooms. I just want to be able to walk in there without needing a tetnus shot, if needed)
dishes (empty and fill)
clean dinner table,
13yr old will help/cook dinners at times
vacuum occasionally
keep bathrooms tidy, but I clean (clean occasionally)
bring in firewood, shoveling snow
help dad with cars and other maintanence on vehicles or house
Daughter (6)
put silverware away from dishwasher,
clean up after herself when eating, playing, homework
most of the time makes her own breakfast and snacks,
clean her room (again, as long as I can get in there it's good. Then we get in there together for a big "sweep" once in a while)
put her clean clothes away from laundry room
Susan, I know what you are saying. My husband and I have often talked about how different the responsibilities were with us and other kids when we were younger. We have made a commitment to teaching our kids to help family and friends and have good work ethics. It's so important. Our children can be very busy with school, sports, church, music (as most other kids are also) Our boys will soon be working, so I'm guessing there will be a shift and there are times when we, as parents, need to cut them some slack on household chores.... but it is important for children to have responsibilities in the family "house". They too will have children someday. Who will pass on the legacy if they don't learn these important, I think basic, principles now?
