A week ago I called Sam Bent, another software engineer at Microsoft, twice for help. The first time went fine, but the second time I had his full name in my head when I dialed the phone, and I opened with, “Hi, Sam Bent.” It didn’t sound like, “Hi, Sam Bent?” as if I was checking if it was him. It sounded like I had used his full name like a first name.
When I answer the phone, I usually move into another room for privacy and so I won’t distract others. This seems natural and reasonable to me. I talk in a normal tone and no one has ever complained that they couldn’t hear me. Others seem to either think differently or don’t realize they’re being obnoxious. They’ll sit right next to me and carry on their one-sided conversations at a heightened volume.
