Last night the enlarged family went out for a meal at a carvery in a pub -the Toby Jug , Ewell , Surrey- to celebrate the double birthdays of Dad and my niece Francesca . Dad was 83 and Cesca was 28 . Poor old Dad ca n't hear so well in company so I had to sit next to the birthday boy and made sure he never missed the conversation .

Generate a question about the above context.
Why was dad sitting so close to the celebrate ?
