If you feel they deserve a good answer, ask them to phone you later or arrange for a specific meeting, instead of whispering in the middle of your child's piano recital or in the dugout of your Sunday softball game. Conversations dont always go like movie dialogue, where you can understand everything that is being said and there appears to be some type of logical thread to the train of thought. Real people do not talk that way. They talk too fast, skip sentences, and get angry before the breath is out of the kind syllable that preceded it. If you are not carefully monitoring the situation, you can look like a total fool.
Some Witches prefer never to come out of the closet.
They see the Craft as a totally religious belief and dont feel the need to share it with the world in general. There is nothing wrong with this as long as you are completely comfortable with it. I have a friend who feels this way about the practice of the Craft. Although she frequently mixes with magical people, discussions on the Craft with normal people are usually off-limits. Let me tell you what I myself have experienced with telling others that I practice the Craft and if you wish you can email me and let me know what you think of the outcome of it.
