     It is Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time. Today is

Sunday again. I get up very late. I look out of the window. It is dark outside. "What a day!" I think.

"It's raining again." Just then, the phone is ringing. It is my aunt Lucy. "I arrive by train", she says.

"I'm coming to see you."

     "But I'm still having breakfast," I say. 

     "What are you doing?" She asks.

     "I'm having breakfast," I say it again.

     "Dear me, Do you always get up so late? It's one o'clock!"
