It's a pity Jack has treated her mum so badly at times (receipts many threads ago) or used her shielding status for sympathy gains during lockdown. Also Jack all of your awful behaviour during the last few months gains you the wrong sort of notoriety which can affect your family too. We warned you to stop posting personal stuff about your son in case his peers use that info to bully him. Indeed its something you have claimed in the past. You had to move your poor child to a different school because he was being bullied for your trans status at the time.
Now if that is true, you would think Jack would realise that her online behaviour could be used against her and her family. Especially during the high school years.
I'm really sorry this is happening to your mum Jack, look after her and stay on your best behaviour for the sake of your family.
