Cards

Do you have a card? I'm talking a business card. I have one for my day job, but I don't have one for writing. Should I? When do you do this? Some people say, yes. I should have one for when I go to networking events. The thing is--I'm not published or even have an agent so why should I have one or even think about having one. What would it say? Writer? I don't know so I'm turning the topic to you guys.

What are your thoughts?
Should an unagented, unpublished writer have a business card?
If so, what should it say?

Have a great day!!
