i think it's hard to be friends or lovers with a writer. here's why:
1) you have to be careful of what you say, because the writers mostly take every word of yours literally and try to find the meaning in it. say what you mean, and mean what you say.
2) you also have to be wary of your grammar. those people, whom you know as writers, are grammar nazis. if they don't correct you in speech, fret not; it has been done in their word-mazed minds.
3) they will rant and rant and rant, because written words are what cool them off without having them to speak aloud. curse words, words which carry a tune, words which burn into brains... hear them out. do not be lazy to read their rants if they trust you with it. (they could rant about you TO YOU in the end.)
4) this is the hardest part. just remember that they will write about you no matter who you are or what you've done (or maybe you haven't even done anything). these people will write about how they see you. and most of the time, those writings are not so favorable. if you do not want to (literally) end up in their bad books, beware. their words may not last in ink forever but embedded into the hearts of those who read them.
happy reading and living with a reader!
for now, im stating the difficult/negative parts of knowing a writer. please look forward to the second part: perks of knowing a writer!
