I FaceTime my friends/family every night. We'll prop up our phones on our desks and eat dinner "together" or just mindlessly surf the web and share links to songs and videos. Sometimes we won't even talk at all if there's nothing to talk about, but it's still comforting having each other's presence on the phone. We'll chat if a topic of conversation comes up but it's nice not feeling pressured to talk as we carry on with our mundane tasks around the apartment.
