Breakfast or lunch

It was Sunday.I never get up early on Sundays.I sometimes stay in bed until lunch time.Last Sunday I got up very late.I looked out of the window.It was dark outside.”What a day!”I thought.”It's raining again.”Just then,the telephone rang.It was my aunt Lucy.”I've just arrived by train,”she said.”I'm coming to see you.”
”But I'm still having breakfast.”I said.
”What are you doing?”she asked.
”I'm having breakfast.”I repeated.
”Dear me,”she said.”Do you always get up so late?It's one o'clock!”
