Sometimes I feel writing spoiles reading. When I send many emails to friends, I find low the speed of reading their replies. On the other hand, writing improves my speaking and I can use more creative words in speech without thinking more or spending much time to look for what a suitable word, phrase or sentence is supposed to be said. It might be an old opinion that I agree on, as teachers used to take apart four skills and evaluate separetly productive and comprehension ones. Writing and speaking derived from productive skills build a good bridge to each other. On the contrary, listenning and and reading are able to develop themselves. In my opinion, human being has special chracters that he or she is able to recognize which one is good or should be improved.
