Welcome.
I am active, but slowly becoming inactive. Like you, I don't want to lose family by DA or DF. (More if you read my biography)
I am not really able to preach, like you. Unlike you, I decided to quit the School. I still comment.
If I go out in field service (don't much, just turn in a couple hours) I share a scripture and offer a Bible study.
Nobody is really interested if you use the direct method. If someone says YES, turn them over to a
pioneer. (If you feel guilty doing that, start the study, on the first or second visit say
"I would never google JEHOVAH'S WITNESSES or WATCHTOWER. There's too much hate information there."
They will check it out.
