Is this weird to you?

So I’ve been staying with my grandmother on my dad’s side for quite sometime, just until I get back on my feet right… but I am currently in the process of moving …anyway anyway she has this new husband who I think is very weird I have plenty of reasons why I think that but it’ll take me all day to explain . But i noticed everytime I go in to use the restroom and come out , one of them go in just a side note i noticed every since my grandmother has married him she has not been the same , she act very strangely now , we were idk somewhat close growing up i didn’t know too much about her but as a kid I went to her house often and loved it , especially holidays. Anyway since I moved back to my home town I’ve been staying with her she was nice enough t let me stay… so I noticed everytime I come out of the restroom either her or her husband goes in right after, mind you it’s only 1 bathroom in the house so I try to make excuses for that very reason , but I mean it could be like freaking 2am and I wake up to go pee and boom the husband goes in … I never hear pee or running water they just go in for a sec or a few minutes then come out and it happens everyday . They both could be dead sleep and I’ll come in the restroom and after I get out they go in & do nothing I guess and then go back into the room . Just a few minutes ago I went in to pee and I came out and the husband went in did literally nothing and then she went in now they are in bed🤔 sometimes when I come back late at night they’ll be sleep but soon as they hear me make one little sound they both get up and start moving around coming in the area where I sleep… idk it’s all strange especially the bathroom thing. Am I tripping or do you find this a little weird too ?
