I was fresh out of high school when I started "witnessing" to my friends. ( 18 years old. 1986 )
Thankfully none of them followed me in to the Org. I have started looking for my old friends. Many are accepting.
After 29 years, it's nice to know that old friends and family are understanding of the dangers of mind control. I usually start with "I recently escaped from a mind control cult". That puts them at ease that I won't be "witnessing" to them any more. It's also an admission of my own mistakes.
