How can I convince my mum to let me have 2 friends sleep over?

[Grace]

I asked my mum is my friends ( for security reasons I'm using fake names) Claudia and Rachel sleep over my house next weekend, she said no because 2 years ago I invited 2 of my other friends over who go to my school ( again I'm using fake names ) Penelope and Aly. However Aly didn't like me and they both left me out, and it was like oh okay. Claudia and Rachel both go to my drama school ( which I attend on weekends.) However Claudia went last term but not this term as she was moving or something, so we speak on facebook but Rachel still goes. But me, Rachel and Claudia get on sooo well! And me and Rachel really miss Claudia. Even though I will see her at Rachels birthday party ( SOMETIME IN FEB ( me and Claudia are also sleeping over Rachels) ) I really want them to sleep over!! My mum was like no 1 at a time, I'm not angry but I need ways t convince her. I tried to tell her about how over protective she was and she won't let me go out with my friends ( like outside of the house ) but she just continued going on her laptop and completely ignored me. :/ PLEASE HELP. and Also as I am older than 13 younger than 16 ( no real ages for security ) I should be able to do this sort of stuff to have some independence. Am I wrong or is she?? PLEASE HELP ME CONVINCE HER!!
Thing is None of us can do the weekend after, and then I'm going to India and it's like... grrr:/

I think you should give your mum some time.. To get to know your friends (rachel and claudia) and prove to her that your reccent friends are Way better than your previous ones.. And let ur mum get to know your friends..then she can decide afterwards..
