Jules - I just asked Lottie what she would expect and her response was. 'If I was working full time and earning money, of course' and that she would expect it too be linked to the amount of money she was earning, ie: a percentage. I said would she think £100 was reasonable, she said yes, and more if she was earning a good salary. She then added ' how old are they...when I said 21 she said 'woow, tell her to get out - does she realise how much things cost ?!). Since she was 16 she has had an allowance - this allows her to buy everything that she needs ie: clothes, make up , shampoos, pocket money for cinema, meals out and birthday presents. She has leant to budget effectively and understands the value of money. When in Turkey she spent more than her contracted minutes on her phone, and has automatically deducted that amount from her allowance this month, (without asking) in order to pay us back. She now has a small saturday job and is saving like mad to afford university.
You have to stick to your guns on this one !!
