Day 19: Letters. A new test we just received at work, which I brought home to practice and have not looked at since (see above excuse about the squirrel in my house.)
Day 20: 4:00. I was about an hour late on this one, but here's a tree at church, where I was hanging out at a picnic.
Day 21: Calm. Here's the kitchen windowsill, which is where I first spotted the squirrel. Now that we're squirrel-free and all this stuff has been thoroughly cleaned, I feel much calmer, indeed. :)
