“I waited years for the train / bus/ taxi.” Mmm, You didn’t actually did you? You waited a while. Imagine if you had waited for years, slowly accumulating things like a portable shower and loo, fresh clothes, a foldaway bed etc. When the train /bus/ taxi finally came all of your stuff wouldn’t fit in it. You will wait many years for a gravy train though!
“I’m up the wall” Are you? Think carefully about it. Are your feet on the ground? Yes. Then you are not up the wall, you’re just harassed.
“It’s boiling” /“It’s freezing”Our exaggerated temperature related superlatives know few bounds.
“Politicians are all the same” What do you mean? The same person? They all look different on the TV.
“There’s no smoke without fire” Ahh, but there is. It is possible for something to smoke without being on fire.
“He/ She was talking a load of rubbish” I think what you mean is that you didn’t agree with their opinions and of course anyone whose opinions differ from yours is completely wrong.
“I’ll only be two seconds” Come off it. You can’t do anything in two seconds except turn your head a little bit. Nobody expects pin point accuracy (“I’ll only be eight minutes and thirteen seconds.”) but two seconds is very much less than you will be.
“I don’t want to gossip but….” You do actually want to gossip don’t you?
