Writer Wednesday: Hi, My Name is Kelly and I'm a Writer

One of the hardest things for me is telling people I'm a writer. I know, you're probably thinking that I have a writing blog and an author website and I'm all over the place online. That's true. But when it comes to face-to-face interactions (at non-book events), I have a really tough time telling people what I do.
You can put me at a book signing or a school visit and I'll talk about my career until you beg me to stop. But introduce me to someone outside the industry in a normal everyday setting and I won't mention my job unless I'm specifically asked.
Why is that? I'm not in any way ashamed of what I do. I love my job. I couldn't ask for a better one. Yet I'm always afraid to tell people I write books because of two main reasons. First, I don't want people to assume I'm going to ask them to buy my books. You know that spammy author who can speak of nothing but their new book. Yeah, that's not me. Second, I hate when people ask me how well my books sell. It's like they expect that since I write I must be on the NYT bestseller list. Yeah, doesn't exactly happen that way.
What about you? Do you have a difficult time telling people you're a writer? What are some reactions you've gotten from people when you have told them?
