A rude person is defined as someone who is <em>"offensively impolite or ill-mannered."</em>

Unlike those two words, there's no direct connection between <u>strange</u> and <u>pleasant</u>. Also, <u>cowardly</u> and <u>brave</u> go on opposite directions. Which leaves us with <u>loud</u> and <u>noisy</u>. Loud can be defined as <em>"producing or capable of producing much noise; easily audible."</em>
