They do swimming at school for 30 minutes once a week.
Conversation this week
Me "did you do swimming today?"
Dd "Yeah"
Me "Any good?" (It can be a bit tedious)
Dd "It was fine"
Me "Right-o"
5 minutes later, as I bung her cotume in the wash
"We had extra time at swimming today, came back with Miss X's class"
"oh, why?"
"Well We couldn't do a mile in half an hour"
"You swam a mile...."
You get the picture?
I'm dead proud of her
