Salve, mi amice!

Colloquendo --> colloquentes

I know, in Italian it would be working just this way, but not in Latin, dear Alex.

"cum virtute fac"?
Did you mean: "cum virtute age"?

And the word order has to be changed too:

Homines colloquentes...

It can be also expressed in ablativo absoluto: Hominibus colloguentibus... if you want to say: "People while talking(are getting to know each other)".

Cara Aneta!

1) "cum virtute age"

2) A rough bridge would be "It's by talking (to each other) that people understand each other".
Sincerely, I am not sure that colloquentes is the best translation of "by talking". I think that gerundium modus declined at the ablative case (in which way?/quomodo?) would convey better the source text.

I see, Alex. I know what you meant now. You are probably right.
Let's see what the bridge will say, ok?

Hi Lilly!
Can I have another bridge, please?

Alex's bridge is correct
