You are always trying to understand it in context, even if, as far as you are concerned, at that point in time, it has not necessarily anything to do with you, you still want to know why those people are laughing.
Si cerca sempre di contestualizzare. Anche se, per quanto vi riguarda, in quel momento non vi coinvolge direttamente, volete comunque capire perché  quelle persone stanno ridendo.
