WHO WAS THAT??

So 4-5 yrs ago I was spending my summer vacation at my grandma's house with my cousins & parents when the incident took place.

That night my grandma was out to some function so we all had dinner & we were about to sleep. We all cousins were lying on bed & talking. (Our moms were talking in another room.)

Suddenly one of my cousin brother felt thirsty so he said " l wanna drink water so drink from kitchen and be back" we said ok & were engrossed in talking. He came back after some time.

After some time my mom came to kitchen for some work. & She asked my cousin brother why he kept the door open ( The door not open previously) So my cousin brother replied grandma came home & she told me to open door. My mother was astronishied & said hope you are not joking because grandma just called now & was telling it will take her 1 hr to return

We still don't know who it was!!

Note- ( my brother just opened the door & turned towards kitchen to drink water so he didn't see grandma comming in)
