I saw rich beggars and poor beggars, proud beggars and humble beggars, fat beggars and thin beggars, healthy beggars and sick beggars, whole beggars and crippled beggars, wise beggars and stupid beggars. I saw amateur beggars and professional beggars. A professional beggar is a beggar who begs for a living.
