This isn’t a fine example of camera work. The ‘film’ is still a treat: seven-month-old Nemo blowing bubbles in her wading pool.

She started doing this two days ago when we filled the pool for the first time. I kept trying to catch her in video, but she was too interested in what I was doing. This morning, I found that if I stick my hand in the water and swish it around, she joins in by ducking her snout under the surface and bubbling.

I’m melting, and it’s not because of the heat.
