Buy a role of duct tape & tell her that it's for her & you will use it if she doesn't stop continually talking about her boyfriend...tell her you need quiet time to study & the iscessant chatting is driving you up the wall & making it hard for you to concentrate on your studies.
I have seem TV depicting people who non-stop talk...I can just picture this with her gasping for breath between each sentence that just keeps going on & on....it would make a good cartoon....lol
