the struggle of sharing a kitchen

i am STARVING. i just went for like a 1.5 hour walk and i want to eat. but my flatmate has friends in the kitchen and i just want to make my food in peace but NOO because he wants his friends in the ktichen. this happens like 3 times a week n me and my flatmate just starve because we arent in the mood to deal with epopel >:(
have some consideration for ur flatmates
