I'm afraid I sparked a huge row, by saying that she can barely operate the microwave and should never have been given a license.
History: FIL is a farmer, got dementia. MIL asked cops to store guns when his licence was revoked. She was scared that he would go mental if the guns were permanently disposed of. The policeman advised her to get a licence instead.
My point is that an elderly person does not need a gun. Ever.
