Strange behaviour

Mummy can't walk or see too well. That means she can't do lots of things. Granny and Baba say she does very well and how understanding I am.

When Daddy had a quadbike for the day Mummy decided she would go with him for a burn up on the back of the bike. She looked really happy and smiley sitting there clinging on tight to Daddy. Lucky Daddy.

When they'd left on the bike, Granny and Baba said it was great that she wasn't letting anything stop her. Great?... so why did Baba wipe his eyes?

Aren't grown ups strange...
