Hi Faithful Witness, For someone who has not prepared much to overcome BITE control (and has low blood sugar) you did good.
What did you learn from this experience? Did you learn that you must be more prepared? Did you learn that you either must have some excuse to make an appointment when they can come back, or to have something for you to boost your low blood sugar? Did you learn to always ask (in an inquiring tone of voice) where is that in the Bible and to ask more questions that lead the JW to trip over the WTBTS's logic and thought-stopping platitudes? Did you learn to forgive yourself for making mistakes with JWs who you don't know so that you are better prepared to help JW family and friends?
Remember to be prepared and to control your emotions.
Peace be with you and everyone, who you love,
Robert
