Gus learned when to floss. Although that would make mom proud that's NOT that kind of floss we're talk'n about.
We're referring to The spelling floss rule. Gus learned that in a one syllable word with one short vowel ending in f, l, or s you double the f, l, or s as in the word cliff.
Example: The horse climbed the grass hill and almost fell off the cliff.
It's quite a thrill to see that Gus's teeth are not a mess. They still shine like glass or polished brass.
Still having fun in tutoring at DMC with Juliet.
