the present Mrs Hughes could probably spend a whole day listing my irritating habits, but she has a mere two - which are actually connected.
She holds a conversation with me when i am in another room, and therefore unable to hear what she is saying, but able to hear her voice so i know she is saying somethimg to me.
In tandem with that, when I am upstairs and she is downstairs, or vice versa, she will call me to her, and in the time it takes for me to move to within earshot and answer her properly , usually four or five seconds, she will have called me another tiwce.
In the grand scheme of things, these hardly count as irritations - they barely irritate me , so I am aware of how lucky I am.
