to be clear, the text has never confused me. When my interpretation is challenged, I keep the door open to the possibility that I might be wrong - in the past couple years I've learned I've played some rules since time
immemorial like vehicle movement, charging, critical transfers, and others incorrectly. Just wanted to clarify that my second grade reading skills are indeed not deceiving me.
