I can be loud--really loud. Not obnoxious loud, not loud when I speak normally, just loud in volume when necessary. I often joke that it's because I'm the daughter of a drill sergeant, but regardless of the reason, if a group of people at church want an auditorium of milling adults and kids to be quiet so we can pray and no microphone is available, no problem.
Though I spend a lot of time quietly writing and putting together resources, love solitude, and don't consider myself particularly chatty, I never really thought about what it means to be too shy, too quiet to talk about something when necessary. For some reason I assumed that most church communicators were people who didn't have a problem getting their message out when they wanted to and that the tools I create for them simply helped them do, in perhaps different or more professional ways, what they were already doing.
