ORDINARY PULLING AWAY (belongs to the age)
Talks normally with friends — the door closed only towards you.
Has interests, just does not share them with you.
Opens up occasionally, when the moment is right.
WITHDRAWAL (not puberty)
Has stopped with friends too, not only with you.
Lost what they used to enjoy — including things that mattered.
Sleep or appetite has changed.
WHAT YOU CAN TRY TODAY (with both)
Be nearby without questions. A car journey together opens more than a face-to-face talk.
Do not ask “what's wrong”. Say what you see: “you've been out less these last weeks.”
Keep one shared meal a day. Not for the conversation — for the fact that someone is there.
