Hateful things
One is in a hurry to leave, and a visitor arrives who talks on and on. A person who interrupts a story to say that they already know it. Someone who reads a letter that was not meant for them. A dog that barks at a guest one is trying to keep secret.
Annoying things
A person who does not answer a letter, and then complains of being forgotten. One who sighs loudly and will not say why. A mosquito, thin and whining, that announces itself at the ear in the dark.
