I think that when I get around to querying (if I'm still even under eighteen by then, who knows >.>) I'll leave it out. I'd like my query, and ultimately my writing, to stand for itself and I don't want the agent to get any unintentionally formed prejudices going. There is the other side of that, that my age (14) is a novelty (in a good way) more than anything else. But if I was an agent, I'd be wary of taking on a client as young as I am. Fourteen-year-olds, on average, are not going to be as good at writing, or as mature and reliable when it comes to business dealings, as older people are. That's just obvious. Now, by the time I start querying I'm going to make damn sure I have confidence in my writing and in my ability to handle the hardships of the industry, but an agent will have no way of knowing any of this. So, I'll just not mention it until I get that offer of representation, at which point my new agent will hopefully be astounded in the good way.
