Constructions that bring to mind the unspoken

Under the heading Thank you can be the hardest words, FT columnist Andrew Hill writes:
“ ... dispatched his chief financial officer, ..., with a brief thank-you – before pointing out how their working styles were not well matched. (Perhaps the clue was in his use of the phrase 'I want to thank Liz' – a construction that always suggests to me the unspoken addition ' . . . but I just can’t bring myself to do so'.)”

The expression  “a construction that always suggests to me the unspoken addition... ” is an excellent example of the sort of subtlety of language that should be available to 'into mother-tongue' translators but only very rarely to 'into L2' translators.
