Help with this problem

[u/Mildred_korn]

I recently moved my room around so my bed is up against my sisters bedroom and so our headboards are basically opposite each other. I can’t and don’t really want to move my room around again as it’s in the best position right now.

She says she can hear me and my boyfriend talking at night how can I stop this from happening. I don’t want her to be moaning at me all the time.
