The park

Mummy, daddy, and Grandma all seem tired today. I don't know why, I'm not causing them any trouble am I?
Mummy and daddy took me out from home because "the sun" was out and "the sky" was "blue". We went to "the park" where I saw lots of "green grass" and some funny little things saying "quack". Mummy and daddy seemed happy and made funny sounds called "laughing" when I did this thing with my tongue.
