Besides being a waste of time for those doing it, AND being an easy way for the Society to inflate its reports of time spent in the ministry, cart witnessing is also taking up space. I live in a hot city in Brazil. Today, the JWs decided to set up their cart in the shady spot of the bus stop, where people going to work have to wait for the bus.
You could call the transit company and complain. They are taking up valuable space. My sister and I called to complain where we are and we never see them anymore.
I have to ride past a cart on my bike every wednesday and the same old vinegar tits sister that persecuted me at the hall sits there pretending she doesn't see me. I thought of taking a longer alternative route, but then thought screw em I 'm not going to let them dictate my day.
You should wave and smile and let her know how happy you are. Let her day be ruined because you aren't a miserable being in the world.
