I was impressed by your use of metaphors, sarah, just like OlgaBernice has been; i have to admit that, as a wannabe writer, i love to use them too. I perfectly understand you when you say that they are useful to explain emotions. I've a very emotional and passionate carachter and i can say i live through my emotions; but it's hard to explain emotions&sensations using words, because in my mind they are made of images and feelings. One could use stream of counsciousness to explain it - but i'm not a Virginia Woolf or a Jame Joyce, i'm not good enough to make something likle this. I've always found metaphors the best thing to sort it out. Even if im not poetical as, i'm sure, you are, Sarah, i like using metaphors too, even speaking in everyday life. My collegues, in the shop, mock me gently about it. When i was at High School, my classmates (in Italy we don't move from a techer class to another with multiple courses: a class i made of the same people for 5 years and has its own schoolroom; teacher go to their classes, not the contrary, so you are always with the same people)had made a sort of "register" when they wrote down my metaphors - to mock me, but i liked it!
BTW, thanks for sharing this thoughts with us, Sarah.
