one positive thing i can say is that recently a friend of a friend of mine has come back into the truth after a couple years of being inactive/worldly
and she realized the world has NOTHING to offer after living in it and doing all those things she thought she was missing out on, she said she has everything she wants and everything she ever wanted in life, and she's not happy, because she doesn't have Jehovah
and now she is back and regrets wasting all that time
so you never know
yeah i've learned never to give up on anyone. with my friends, i call them like once every other month to let them know that i care and that the door is always open for them to come back and i will be the first one there for them.
