Welcome.. and I agree. it is the age thing.. my son went through it too... he is 16 now and so i am dealing with the teenage rudeness...

All you can do is teach her it is wrong and hurtful to lie.. and that is causes you to have a hard time trusting her... and with the rudeness.. a told my son if he wanted me to do things for him. he was going to have to learn to be nicer to me...

When you grow up in a world where nothing makes sense, and its not even close to being a normal way of life..its hard to know what is normal...I have found that out with my son and his behavior...

I never learned how to be a normal little girl.. or teenager... was never really allowed to be. so i didn't know what was normal for him either ya know..

Stay with it.. follow your instinct...You wil be fine.. and so will she..
