"never" isn't listed in group 4! I figured it out but just calling attention to that. I don't know if it can be used as a rule, but until I realized it was just omitted, I assumed we had to translate "never" to "no" and put it at the beginning of the sentence. "Lazy cats never develop heart disease" becomes "no lazy cats develop heart disease"

"never" was not listed in the group 4 list in the lesson. So I got tripped up when it appeared in practice
