Follow up from a post of mine on the '... mildly annoy you' thread, having told the head guy in a private DM that my kid would be leaving the team, he announced it in a voice note on the parents whatsapp group chat, and then kicked me off the group. Within two days we had a trial with another team, four days after that he played a friendly for them and they asked him to join there and then. Job's a good'un!
The old coach sounds like a total bellend, good job leaving that team.
