"Let's talk a little about us."
Translation:Parliamo un poco di noi.
This sentence is not in the indicative mood and it doesn't belong here. The approved translation: "Parliamo un poco di noi." is in the indicative mood. It means: 'We talk a little about us' which does not correspond to what is given. I don't know what it is in Italian but when you say something that is hypothetical or a wish like: 'Let's talk about ... ' is it the subjunctive? Anyway you haven't introduced this yet.
