I've been drinking wine since I was a child. I really don't understand all the fuss about ages. As long as a child wasn't a bother, no one really cared about it in my time.
That said, if it is all right by you, Mistress Kallian. I will occasionally have a young friend with me. He may be eleven. But, he is more mature than some adults I have met. And, has been around taverns and inns his whole life.
