In your defense, I hafta say that I think it's a bit different when a mother of children has to holler now and then from another room.
It's just that when my mother does, it's for inconsequential nonemergencies...like crying wolf. It's as though I would think as an adult that she might recognize what strain it puts on me. (Well, not now...now I expect the strain. But for the last decade, it's been one of her most maddening behaviors.)
How many hundreds of times would I explain that when she calls, I'll come, but she needs to give me a moment to set aside my laptop, get off the bed, walk around the bed, out of my room and down the hall where I'll be within her hearing.
She KNOWS she can't hear me reply. But she'll stand at the base of the stairs hollering and then mutters something sulky, or whines, and lays a big guilt trip over the fact that it took me 10 seconds instead of 2.3 seconds to go, yes, Mom?
I don't begrudge it now given her years, but it is one behavior I resented so much. I am not a bell-pull! (She has always loved having a little bell in her room that she could tinkle to call someone when she needed a tissue...AAAAAAAAAAAAAAARRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGLLLLLLLLLLLLLLLLE!)
OhI ain't no saint.
