Rule reminder
Register awareness is essential at B2 level. Idioms like 'prendere le distanze' appear in newspapers and official statements. Others like 'sudare sette camicie' or 'montarsi la testa' are too colloquial for formal writing. When in doubt, ask: would a journalist use this in an article?
A friend texts you: 'Come ti è sembrato il mio discorso?' You want to say he embarrassed himself. Which reply is appropriate for an informal text?
