22 year old daughter acting like she should be on a silver platter?

22 year old daughter is yet at the blame game stage where everything and everyone is at fault for her failure. She has been a problem at home since a teen and was kicked out due to the lack of respect and running of her mouth. Now she is in her parents home after they opened their door to ist her however she tries to run over the family by running her mouth despite being reminded that she is a guest. She has had more then one instance of yelling and using bad language as well being condescending to one member or another when she is in discontentment. I cant help but feel bad for the parents because they opened their doors to help her because that is what parents do but the kid is expecting them to fork over expenses. She had been told she has to pay rent and agrees to the face of the parents , but when the back is turned she will complain about it because she feels she should not have to because she is " daughter" and that her parents are bad people because they expect her to be responsible. The last out break that this poor family has had to deal with is that she wants her drivers license. THis family drives sticks and the girl can not drive this type of car. She expects the family to get her an automatic car so she can practice her driving and expect her family to pay for the drivers license as well. I walked in on her running her mouth to her parents when i went to pick up the mother for work cause we share drive. This girl at 22 should be booted out on her bums cause i know if she was my kid talking to me in my house that way and then telling me she isnt leaving when told to leave... it makes me angry that she can be this way and play victum. I cant help but be angry for the family because this girl was given the silver spoon by a grandfather that gave this kid whatever she wanted in the way of money and now that she has to work and support herself she pulls this garbage of blaming her parents for anything and everything. Being a parent myself, we parents are not perfect but as long as you take care of what is yours dispite family dynamics... no one deserves what this trouble making daughter is doing to this family. I am venting here cause really my friend is a hard working woman who does not take crap .. but it seems to me this free loading daughter drags her down to a point i am about to open my door to her and let her move in with us until she gets her own place. What do you think about the way this so called child is behaving?
