My daughter will be 15 this summer.  She is a good kid - doesn't act out with drugs, alcohol, etc. But the problem is how rude and disrespectful she can be toward me.  I am separated from my husband - her step-father and father of my 3-yr-old son, but he is still in our lives to some degree.  She is nice toward him and then rude toward me in regards to me allowing him around.  I call her on the rude behavior, but it seems to go no where and i feel that we fight too much.  I guess i need to toughen up, but i really want to be able to communicate without such strife.  I just get so stressed out and frustrated with her.  SHe stays in bed until noon, then i have to prod her to do her chores.  I would love some advice on how to encourage responsiblity and respect without nagging and yelling!
