dd1 says i dont listen properly and i dont understand her. we are having a few "kevin and perry" type arguements lately and i admit i dont understand why she is being like it.
eg. the bath mat had slid right up to the cupbaord. dd1 says "look the bathmat is underneath the cupboard but i didnt do it". i said it wasnt underneath but was against it. she repeated" i didnt do it". i said i knew she didnt do it, nobody did it, it wasnt underneath it had just slid. she then erupted into a screaming fit that i didnt understand her, she hadnt done it but she was just saying she hadnt done it, she knew i wasnt blaming her just saying. 
eg. i fetched 2 bobbles for dd1 and 2 bobbles for dd2 to do their hair. dd2 picked up her small bobble and said "my bobble". dd1 picked up her 2 bobbles and screeched "no they are my bobbles not yours". i said dd2 had picked up her own bobble not dd1s so they both had their own bobbles. dd2 (2) says again "my bobble" whilst holding her own bobble. dd1 screeches "theyre my bobbles" whilst holding her own bobbles. i said theyre was no need for shouting, they both had their own bobbles and dd2 wasnt trying to get dd1s bobbles. again dd1 said i didnt understand, she knew they had theyre own bobbles, knew dd2 wasnt getting hers and knew dd2 was talking about her own bobble. i asked her why she was screeching "no they are my bobbles"then. she said i wasnt listening to her.
its like she is trying to argue when there is no arguement.
she is a bit jealous of dd2 and will say she is. i try to be fair with them. if 1 is holding a toy the other has to wait till they have finished. dd1 wants whatever dd2 is holding, asks for it and if told no just tries to snatch. when i say no, she screeches we never give her anything.
am i missing something, as its only been this week she is saying i dont understand her.
outside the house she is meek and quiet and doenst say boo to a goose.
