a woman shouldn't be called by sweet names, 'cause she can also be bitter when neglected. a woman shouldn't be called a princess or a queen, 'cause she can also be a knight when hurt. a woman shouldn't be called love, 'cause she can also use her intelligence to know of you are cheating. a woman should be called by her name, 'cause it is the most lovely thing she will hear from the man she loves.
Personally, if I get involved into a relationship, I prefer to be called by my name. I just love the thought that man you love says your name over and over with such love and affection :)
PS. I really enjoy lower case in writing my poems. :)
