When we talk, we sometimes don't

I ask my mother what I should do after this rough situation.
She tells me the life story of a woman she met at a hair salon.
The stories seem to be unrelated.


My sister tells me we need to find out the name of our postman.
I think how strange of her it is to want to invite him for a meal.


I tell you I have to buy 3kg of food for the dog.
You don't understand why I need 3kg of salt for cooking.


I am unsure of what to think about this man and ask her for advice.
She tells me that her mother too has reached menopause.


He is desperate after having failed his exam again.
She tells him there is more to life than fun and that he should stop being so selfish.
