How do I choose between "imperfetto" and "passato prossimo" in a past sentence?

Imperfetto and passato prossimo are both verbal forms that are used to describe actions that took place in the past. However, they cannot be used in the same way. Let's now give a look at both cases separately.Imperfetto is used to describe something that used to be part of your routine, something that you used to do on a daily base or at some point of the week or the year. You can use imperfetto if the phrase you're thinking of has the form used to in it. Let's check some quick examples:1) When I was younger, I used to go to France every summer --> quando ero più piccolo, andavo in Francia tutte le estati2) After school I always used to have an ice-cream --> dopo scuola, prendevo sempre un gelatoOn the other hand, passato prossimo is used to describe something that happened in a specific moment in time, generally not too much time ago. You can generally use passato prossimo to translate the past simple form. Let's give a look at some examples:1) Yesterday, my mom bought me an amazing red scarf --> ieri mia mamma mi ha comprato una bellissima sciarpa rossa2) A couple of weeks ago I went to the best restaurant in time --> un paio di settimane fa sono andato al miglior ristorante della città
