suppertime every night its the same routine, bang my head on light fixture hanging down on chain

for past three years since my mother died, i fix supper for dad and myself. he will not eat in the dining room, but prefers sitting in corner of small kitchen. i am wedged into corner next to the refrigerator sitting on a fragile chair made of toothpick like material. he literally stands over my shoulder or reaches around me to wipe every drop or crumb from counter. he grabs the utensils i am trying to cook with if i lay it down for an instant. and must make a pot of tea while im cooking, which will trip the breaker. after eating i go in the tv room and everything is at a different angle, he is obsessed with swiffering the floor!! i have to laugh to keep from screaming like my siblings would do. old people will drive you insane if you allow them to😂😂.
