Do you look and act like an author? I have a friend who knows me from karaoke, and she read a book of mine and came up with a deliciously left-handed compliment: “I had no idea you were so deep! I mean, you’re so goofy all the time!”
A lot of people also assume that athleticism and writing do not go together. I used to love showing up for a local poetry reading straight after my softball games, in full uniform, just to mess with this notion (well, and also because I didn’t have time to change).
