Jaja, nur wenn das Miteinander gerade so wichtig ist, würde ich es nicht weglassen.
talk with each other

Vielen Dank ;)

AE: talk with someone
BE: talk to someone

Here you could also say 'talk together'.

Oh, and when there are just two people, "one another" is more usual. You can talk to one another.

Unless there is any particular need for brevity, I think "talk to each other" sounds friendlier and more conversational. Using just "talk" without the reflexive object is also correct but sounds a bit colder (to my ears at least).
