Playing scratchies

Sometimes I get to help scratching pieces of card with numbers underneath. I don't really understand what I am doing and why sometimes mummy and daddy get excited and I can go with morfar and buy new ones and other times no one gets excited. I simply think it fun to scratch! Today the weather wasn't too good and some snow flakes have fallen from the sky. I got to try out mummy's new yoga mat and she gave me her old one. So now I have my own yoga mat. I love yoga, but I cannot understand why daddy is so bad at it and cannot get into the simplest of positions.
