My grandkids think the same thing!! Gets me in trouble sometimes too. My 12 year old granddaughter has spent the last 3 weekends sewing a Laura Engels Wilder costume. I walked her through making the bonnet one day, the pinafore the next week and today she made the dress.
Another granddaughter made an apron one weekend. Then she lost it somewhere at home. I told her she could make another one -- she just looked at me and said "Do you know how much work they are?" She makes me laugh!
