when do you stop being a master and become a mister
Master (form of address) Nancy Tuckerman of the Amy Vanderbilt Complete Book of Etiquette writes that in the USA, unlike the UK, a boy can be addressed as master only until age 12, then is addressed only by his name with no title until he turns 18, when he takes the title of Mr.,[3]:662 although it is not improper to use Mr. if he is slightly younger. Robert Hickey, deputy director of the Protocol School of Washington, states that "use of Master [as] an honorific when addressing boys is considered old fashioned outside of conservative circles."[4]
Jack of all trades, master of none The "master of none" element appears to have been added later;[citation needed] which made the statement less flattering to the person receiving. Today, the phrase used in its entirety generally describes a person whose knowledge, while covering a number of areas, is superficial in all of them. When abbreviated as simply "jack of all trades", it is an ambiguous statement; the user's intention is then dependent on context. However when "master of none" is added this is unflattering and sometimes added in jest.[6] In North America, the phrase has been in use since 1721,[7] typically in its short form. "Still better than a master of one" is sometimes appended to the phrase[citation needed].
