When I was little I would spend the summer at the cottage with my grandparents. I would see my parents on the weekends when they came up.
On one occasion my dad was horrified by my smell. I think I was 7 or 8. Grandma hadn't made me bathe all week because I'd spent so much time swimming. Her sense of smell isn't that great.
Imagine my laughter on discovering that my kid, who has also been up at the cottage all week with Grandpa, has also not bathed for a week! Luckily she doesn't smell that bad. Despite sleeping with the big stinky dog most nights.
