With that many meetings every day, with tea offered at every one of them, which he could not refuse, because that would be rude, he could not take even one cube of sugar per cup of tea, because that would be many kilos of sugar, he can't even calculate how many kilos, and at that point I realized why he was speaking so fast.
Con tante riunioni  e con il tè offerto, che non si può rifiutare,  perché è scortese, non poteva mettere un cubetto di zucchero  per ogni tazza di tè, perché significherebbe tanti chili,  incalcolabili, e in quel momento ho capito  perché parlava così veloce.
