I generally always right in 3rd person, particularly omniscient, because I don't like to limit myself to the thoughts of one character. However, I keep reworking a short story I wrote last year in first person, and I've noticed that when I write in first person, I do a lot more telling than I do showing. Not it's bad, but I wondered if this happens with other people also. At least with the emotions of the narrator. I find it usually sounds more natural for a person telling a story to say "He made me so mad" than "I grew red with rage."
