I need privacy!!!!!!?

[S]

You are not alone. Its happening to other people everywhere but that's not what you want to hear. There is no magic answer no amazing action you can take just ......time.
Sooner or later your sis will also want what you want and then you'll hardly see her. Privacy for you will come soon enough.Part of being a family member. One day you will look back on all this and smile.
In the meantime do not react when anyone bursts in . Getting a reaction from you will be half the fun, so pretend your pleased to see them. Over time the intrusions will get less and less. And remember. .nothing but nothing stays the same.
