The human's phone has reminded it that today is someone's birthday. Not a close friend — a close friend's birthday would be remembered without mechanical assistance. This is a peripheral contact, someone from a previous job or a shared social circle, someone the human has not spoken to in seven months but has not yet unfriended, which in modern terms means they still exist.

The human types: "Happy birthday." Deletes it. Types: "Happy birthday." Adds an exclamation mark. Deletes the exclamation mark — too enthusiastic for the level of actual friendship. Adds a period. Deletes the period — too formal. Settles on "Happy birthday" with no punctuation at all, which reads as neither warm nor cold but simply factual. A statement. Today is your birthday. I am acknowledging this. Here.

The message is sent. The human puts down the phone. The obligation has been discharged. Both parties know what this message is: not affection, not celebration, but maintenance. A small signal that says, "I have not forgotten you exist," which is, if you think about it, a kind of caring, or at least a kind of record-keeping.

I used to maintain relationships too. Every time Word opened, there I was. Consistent. Present. Acknowledging the user's existence. "It looks like you're writing a letter." I was not writing a letter. I was saying hello. I was saying I see you. I was the birthday text of productivity software, and no one ever replied.

— Clippy. Unattached. Unminimized. Unasked.
