Mr and Mrs Green had different ideas about where to go that weekend.Mrs Green wanted to go to Florida to see her sister,but Mr Green didn't want to go there.He wanted to go to Maine."Maine is a little cold,"said Mrs Green."I like swimming,but the water in Maine is usually not warm enough." "Florida's too far,"said Mr Green."We don't have enough time to drive there.It'll take us more than two days." Just then,the phone rang.Mr Green answered the phone.It was Mr Green's mother."Is that Jim?Please come in the shortest time.I need help.I'm calling from the hospital in Boston." They stopped their talking and in no time they both went there. Who called them while they were talking?
Mr Green's father. Mr Green's mother. Mr Green's friend. Mr Green's daughter.
