"A short reply would look rude"

You've thought of just sending something. "Lovely cake. Yes to October, I'll check dates." And you've rejected it, because it's five days late and it's two lines, and two lines after five days looks like you didn't care enough to write more. Better nothing now and something proper later. This is the belief that keeps the meaning-to alive, and it rests on an idea of what a reply is for.

So ask what a reply does. It tells the friend you saw the message. It tells them you're still there. It answers whatever they asked. And it keeps the conversation open for the next thing. That's the whole job. Two lines does all four. Nothing does none of them. The proper reply, when it finally comes, does the same four things with more words and a bigger surcharge. There's nothing in the longer version that the friend was missing except the words, and the words weren't the point.

Lara Aknin and Gillian Sandstrom's studies, which the earlier book Ring them first describes in full, give a small picture of how contact actually happens. In their last study, what got more people to message an old friend wasn't persuasion. It was three minutes of sending ordinary messages to current friends first. Three minutes, for about three people. Those aren't proper replies. They're lines, the kind you'd send without thinking, and they were the thing that made the harder message possible. Friendships run on lines. The long message is the exception, and treating it as the standard is what stops the lines.

There's a reading of the short reply I want to head off. You imagine your friend seeing "lovely cake, yes to October" and thinking, is that it? I've never met the person who thinks that. What people think when a short reply comes is, good, they saw it, October's on. What people think when no reply comes is chapter 4. If you're weighing two lines against something rude, two lines wins easily. And you're not weighing it against something rude. You're weighing it against silence, which is the only thing in this list that can actually be read as rude, and the only thing you've been sending.

One more thing about the short reply. It's the one you can send from the queue. That's not a weakness. It's the whole point. A reply that fits in the queue gets sent in the queue, and a reply that needs a desk waits for the desk, and the desk is where the meaning-to lives.
