Summarise a long family group chat argument into what everyone actually wants

The family group chat has been going for two days, everyone is typing in capitals, and you have lost track of what anyone actually wants underneath the accumulated grievances. This reads the whole thread neutrally, strips out tone and old history, and states what each person is really asking for, plus any agreement nobody has noticed yet. For whoever gets asked to mediate because they replied last.

You have a family group chat that has spiralled into a long back and forth argument, and you want a clear headed view of what is actually being asked for underneath the noise. Paste {CHAT_HISTORY} below, meaning the relevant messages in order. Read through it and identify what each main participant actually wants, separate from how they said it (tone, capital letters, and old grievances aside). Note any point of genuine agreement buried in the argument that nobody has acknowledged yet. Keep the summary to under 150 words and use neutral, non judgemental language for every participant, without taking a side.
