my friend's father is very careful about spending money she can't buy things unless they are useful so she could never buy anything she wants.yesterday she stole 100 rupees from his pocket and spent it and bought chocolates how long do you think she can hide it from her father?
How old is she? Why does she not have her own money? Of course he'll find out before long and he'll be furious. I would be furious if my children had stolen from me. If young, why has she no pocket-money? If older, why has she no job? Chocolate is a ridiculous reason to steal for, so I suspect she is a child. You do not steal.
^^ Just realised that you mentioned 'rupees' - so you are in India.. It was still a stupid and dishonest thing to do and I suggest that she faces her father and admits her fault before he finds out for himself.
