Let me help you clear away the tea things (= cups, plates, etc. that are used for having tea).
2 the real thing真事；真品，非贗品
The fire alarm goes off accidentally so often that when it's the real thing (= when it really does happen) nobody will take any notice.
3 a thing or two
She thinks she knows everything about raising children, but I could tell her a thing or two (= some information she does not know).
4 a close/near thing
The car just missed the child but it was a very close thing.
5 the thing is
The thing is, my parents like me to be home by ten o'clock.
Can you pass me that thingy - you know, that clip thing for holding papers together.
7 the done thing
Don't forget to shake hands - it's the done thing, you know.
8 and another thing
And another thing, why didn't you tell me you were going out?
9 all things being equal
All things being equal, I'll be at home on Tuesday.
10 for one thing
"Why won't you come to New York with me?" "For one thing, I don't like flying, and for another, I can't afford it."
