Funny, I was a girl scout leader too (still would be if i could figure it out from here--can't get an email back to save my life though). At the begining of second grade we told all teh girls in the troop taht THEY were responsible for bringing in dues, signed forms, etc and "my mom (or dad or grandma or whoever) forgot" was not an excuse. It was THEIR job to make sure they go the forms signed and into their folders and remembered to bring their folders. We had a month or two with lots of forgetfullness, and then when they realized they really were respoinsible they stepped up to the plate.
As a parent, that frustrates me. I understand completely what you are saying. In theory, I agree with it. In practice, it doesn't work in my house. I have 5 kids. The time of day that my kids tell me about these things can be hectic. Sometimes they tell me and I say ok and I just get going on something else. I forget. It doesn't happen often but it does happen. I'll say something like, "Ok. I'll sign it and put it back in your bag...just put it on the counter." Oops!
Recently my fourth grader forgot to bring in a note saying she was after school for something. The teacher wasn't going to let her call home. It turns out that I had H1N1. My twin 2 year old girls had H1N1. My poor husband was trying to take care of 3 sick people and 3 healthy school-aged kids (which is not his routine). We forgot the bloody note. My DD was upset....because we don't normally forget these things. She didn't need to be made to feel worse in the name of "teaching responsibility." It was a tough enough week for all of us.
