Heh. When our girls were young, and whining hard about homework, DH would tell them that he already passed Grade X, now it was their turn. He would help with homework, sometimes a lot, but all the ideas and leg work had to be theirs. The only time I typed something for someone was when she had 15 minutes to leave for school and had forgotten that it had to be typed and printed, not hand written.
There were many children whose parents did do their homework and special projects for them, and it cost my kids a lot over the years, but they KNOW when they've earned something, it was THEM earning it, not us.
