A Believer
On a previous post you mentioned you were at school.
You're young, and at a vulnerable age. If you are not careful you will:
Lose your friends. It doesn't who they are, or how long they have been your friends you'll be expected to drop them. They'll automatically be considered 'bad association' by JW's.
Lose your family. As you won't be celebrating birthdays or Christmas anymore you'll find your family relationships will get strained.
Have limited prospects. JW's are against further education, and university in particular. This is why there are so many jokes on this forum about elders being window cleaners etc. You could be a low wage earner all your life as you'll be encouraged to quit further education and focus on what the WT considers 'theocratic activities'.
I'm sure the sistes that called were very nice (was one of the them hot?!) but it's a strange world you are looking at entering. On the outside it looks great, nice people who are all smiles in the meetings. But once you're inside you'll be stuck in an endless cycle of meetings, assemblies, ministry and the hierachy in the organisation. Over time you'll find them incredibly gossipy and friendships will only last as long as you keep in that endless cycle I mentioned above.
I strongly urge you to re-read JWFacts and see if you can get copies of 'Crisis of Conscience' and 'Gentile Times Reconsidered' online.
