ABSTAINER, n.
A weak person who yields to the temptation of denying himself a pleasure. A total abstainer is one who abstains from everything but abstention, and especially from inactivity in the affairs of others.
Said a man to a crapulent youth: "I thought You a total abstainer, my son." "So I am, so I am," said the scapegrace caught-- "But not, sir, a bigoted one."
