When my brother and I lived together, we definitely texted each other, either via text or Discord. When we only lived in a 2bdr apartment. If we were in each of our rooms, with the doors open, we could easily just talk really loudly if we wanted to. But we typically had headsets on.
If I'm visiting my family, if there's something I want to show them on the computer, I'll often just drop it into our family Discord. Easier that way.
