what do you do when you are hungry ?

When you are very hungry , others people eat food but not keep it for you. Then what do you do ? If i tell about me i get angry.  If my brother , sister , mother and friends etc eat food and does not keep it for me , even if i am hungry , then i get angry with them. 😞 When i am at home and i am hungry then i wants another person cooks for me.  now tell me what do you do in this situation ?
