My MIL was diagnosed with Alzheimer's some years back. Since then she has had an obsession with shopping, to the point where she visits the same supermarket up to 3 times a day. She's also obsessed with feeding "animals" in the garden, the only things we have visiting are pidgeons. She chucks out any food onto the lawn and has a break down if you try to put it into the bin. Recently, she's been drying tea towels on a hot grill. I was wondering what other odd habits people have observed with their family members ?
