My cousin moved in with us a few months ago. My parents left for vacation a few days ago. They have the master with the master bath obviously. My cousin has made it a habit to use their bathroom and close their bedroom door and lock it. My mom has confided in me that she doesn’t like it and doesn’t feel comfortable and said she was going to say something to her but I’m guessing she never got the chance before she left. Now I understand, there’s about 6 of us who use the main bathroom so she’s probably not comfortable using it. But knowing my moms not comfortable with her locking herself in their room, I feel like locking their door. They have a sliding door so I was thinking of leaving that unlocked so I can get in their once they come back to unlock it plus I have my moms keys but not sure if she has one for her room. She uses their bathroom when literally no one is using the main one so she can’t use the excuse of the bathroom was busy so she had to use theirs. I’m not comfortable nor confident to let her know my mom doesn’t like it because I hate confrontation. I was hoping me locking their door would be enough of a hint that she can’t just go in and lock their door.

She’s in there right now. Already flushed but I can hear her still in there on the phone. She’s been in there for about 20mins now.

My husband told me this doesn’t concern me and to leave it alone. But I feel like I should do something. Like that’s my parent’s bedroom and she’s locking herself in there ?
