The teammate who stopped joking in the chat? Message them directly. Quiet is sometimes a flare.
GRATITUDE
GRATITUDE
A change in someone’s usual pattern is often the only signal anyone gets, and it is easy to miss because nothing dramatic has happened. Withdrawal does not announce itself, and the person rarely has an opening line ready, especially in a group where the tone is light. Being noticed matters even when nothing is wrong.
Send something private and ordinary rather than a general question about how they are. Mention what you noticed, briefly, without making it heavy. Leave room for a short answer, since a short answer is usually how these begin.
Who has gone quiet lately that you could message today?
Free, with nothing to buy inside it.
