Mum s new dining habbits

As usual , sis and i are invited every wednesday eve for dinner with mom and dad. The are in their early 90 s and we love to visit them. Mom always says , no i don t want to eat and picks up now and then a bit from the foot. Many times before dad told her to take a plate and eat properly portions with us. Now she does and enjoys. But it is the first time i see her dining with plastic gloves. The reason is , we have eaten mussels and boy they were tasty.
