When I was a kid, the first demonstration I participated in involved being prepared for preaching under ban. I was pretending to be going Door-to-Door™ with an elderly Sister™. In addition to her sticks-out-like-a-sore-thumb green NWT Bible™ she carried a shopping bag on her arm, with some light groceries in it. She wore a kerchief on her head and was wearing a green sweater over top of her skirt and blouse. I was in a jumper with a white shirt with the long sleeves rolled up.
We went up to a "house" and heard someone yell from inside "Call the police, the Jehovah's are here!" (everyone laughed!) The Sister™ grabbed me and we hid behind a parked car in the alley (the podium) - she pulled my sleeves down. She took off the kerchief and put it around my neck, then she took off her green sweater and told me to put it on (it was like a long coat on me). Next she pulled out a *blue* sweater from the bottom of the shopping bag and put it on herself.
We came out of the "alley" and those "cops" couldn't find us anywhere!
We sure foiled those bastards!
