Likewise, Isaac.
My first name---and still at times what I think of as my 'non-family' or professional name---is one of those handed-down-in-the-family-from-generation-to-generation. When I was growing up my Great Uncle Hoke was "the" Hoke, and everyone in the family called me by my middle name. Only strangers and officials called me Hoke, and it sounded strange to me when they did, for I didn't think of myself as that person. That was my Uncle!
But it was a signal to me that the person who was addressing me wasn't a family or friend, but an outsider.
Only a few people in my close family still call me by my middle name, but when I run into a cousin I haven't seen for a while (I'm not close to many people in my family) they'll still call me by my middle name.
What I was referring to earlier, though, Isaac, was not the middle name. It was that particular....and I think peculiar...habit of using the first initial/middle name. The "W. Blake Gray". It's odd to me: he is signalling that he goes by the name of Blake, and thinks of himself as "Blake", but still goes to the extra specific effort of putting the W. in front of it...but not dignifying, or even clarifying, what the W. stands for. Why? Is he ashamed of it? Does he not like it? Then why doesn't he just stop using it? Why not just "Blake Gray"?
To me it's studied. And pretentious. And I suspect it's some sort of attempt at calling for attention, a "look at me, look at me" kinda thing.
Take you: I didn't know you were conflicted in any way with your name. To me, you are Isaac. You don't sign yourself as I. Andrew Whatever. (Thereby forcing me to wonder what the hell the "I." stands for.
) You could just as easily call yourself Andrew or Andy.
