Hello, advise what to undertake, please, in a following situation. My daughter of 12 years, there is a senior girl of 19 years. Family full, amicable. The Financial position stable. For poor progress at school the daughter has been deprived pocket money, and one of these days we have found out loss 50 griven (nearby 10 $). Also the things of the senior sister taken without demand, for all questions lie and twisting were found out. Family in a shock!

Usually the minimum of pocket money should be at any progress. Talk all together about rules of a joint life in family and how it is possible to settle progress and to distribute or allocate residential zones, itd (usually enough strong problem for sisters), but the first episode of larceny it is better " to lower things on brakes " - without tragedies and drama stages.
