Review each other's changes

[loftusa]

When one of us makes a change, the other should likely be in the habit of accepting or rejecting those changes (just so that we get two eyes on everything). We can keep track in this issue, and post task lists for changes we want the other to accept/reject.

@ebridge2:

• [ ] Reflected Lauren chapter 2 changes
• [ ] Reflected Lauren chapter 3 changes

@ebridge2 assign me back to this issue if you have anything for me to review
