Hindi 'agar … to …' is the if-clause; clear beats perfect
Italian 'se …' lines up exactly with Hindi 'agar … to …' — 'agar baarish hui, to ghar rahunga' is 'se piove, resto a casa'. The impersonal 'si' matches the Hindi general voice in 'yahaan Hindi boli jaati hai' (Hindi is spoken here = qui si parla italiano), where the 'who' stays general on purpose. The real Day-29 lesson, though, is to stop stalling: Indian-English learners freeze picking the perfect tense while the conversation moves on. Italians follow you easily if the verb roughly fits the timeframe — start the sentence, choose the tense that feels right, and reach for 'come si dice?' whenever you're stuck.
