My mum says: "I will be sad after he goes back home." so I can say: "She says she will be..."
But what about: "My mum said she will be sad after he goes back home" - reported a moment ago (it is okay, my teacher says so) but do I have to change the tenses if the person still thinks this way?
"My mum said she would be sad after he went back home." - is this correct too?
