"Remote" is about two people who drift apart and only understand how close they were once it's too late. The speaker looks back on a relationship and notices a painful pattern: the moments when they "spoke" the longest were the quiet ones, and the longest stretches they spent together were spent far apart. Closeness and distance seem to have swapped places. Silence says more than words, and being apart is somehow a kind of shared time.
The second stanza turns this into regret. The speaker calls it "typically ironical" that they "turned our back" on each other only after their hearts had "already intertwined." There's a wry, tired tone in that phrase, as if the speaker has seen this kind of mistake before. The mood is wistful and a little bitter. Nothing is shouted; the feeling sits quietly, like the silences it describes. The title, "Remote," fits well: it suggests a distance that's emotional as much as physical, and a love that can't be reached anymore.
