<prompt> Human: Our 15-year-old daughter has after-school activities until 7pm on Thursdays. Sometimes she comes home first and other times she stays at school for extra help. A couple Thursdays ago when she planned to stay at school, we gave her a 20 bill with which to go to the pizza shop next door and buy dinner during her free time. My wife and I typically spend 15-16 combined when we go there so when we asked her to spend no more than 10, we thought we were being more than fair.That night we picked her up and asked her for the change and she handed us 6.15, meaning shed spent 13.85. When we asked her why, she said Thats how much my dinner cost! Translation: Thats how much the exact food and drink I wanted cost!. It wasnt about the money so much as acting responsibly, not to mention doing what youre asked. There were several choices she could have made to lower her tab, i.e. buying the food she wanted and drinking tap water instead of a bottle of soda, or settling for a burger or sub instead of the chicken finger dinner if she couldnt do without the bottle of soda. But of course, she just thinks were being cheap.Suffice it to say we only gave her 10 today, but I dont think the true message is getting through to her. She has always had a tendency to blow any money she gets as soon as she gets it and were worried this is going to carry forward into her adult life. How do we help her become more financially responsibleaware?  <response>: rparenting
