Writers are not nice people by nature and even less so when one of their own tries to tell them how to walk, talk, and wave simultaneously. Keep that in mind when reading my faint praise for The Glamour Of Grammar: A Guide To The Magic And Mystery Of Practical English by someone named Roy Peter Clark.
Some chapters were interesting. Others I could have done without. Keepsakes were unnecessary. Short chapters made for a fast read. You could do worse with your time.
