M:              ?
T:  Look! There is a big hole in this one, and the other one is broken, too. I think nobody can mend them well.
M:  Yeah, that’s true. Well.             ?
T:  Mum, I’m wearing size 8 now, but they’re a little small. Size 9 is just right, I think. But when shall we go shopping?

M:             . I’ll meet you at the school gate.
T:  Thanks, Mum. Oh, I must go to school now. See you then. Bye.
