How can I convince my mum to let me host a sleep over at out house?

i think that your mom still regards you as a child. well, i guess it's natural for mom's to feel that way. i am turning 20 but i still ask her permission to go on those night outs and such (and most of the time she says no :)) but i just accept her decision because as cliche as it may sound, mothers know best. or at least try to explain your side if you really want to go. you should earn her trust that you can already handle yourself and make sound decisions. however, remember that trust is earned gradually. if she sees that you are already a responsible person and that she can trust you, she will slowly allow you to go on with your movie nights and such. you might even be surprised when she does! that's what happened to me. :) with regards to having a sleepover in your house, i think that she does not allow you because if you are the host, you (or your mom) would have to be the one to prepare for it and also clean up after wards. it's a hle. that's what i think. hope you understand your mom better. :)
