This religion is a cult. If you want to hang out with them fine, but, think very very seriously about joining. Keep asking questions google the shit out of this group there is plenty of horror stories out there from people who been there done that.
The JW religion is similar to scientology in the way it's structured and the methods they use to control members so buyer beware. You owe it to yourself not get swept up in how good it feels and not take this "niceness" on face value. Remember things that appear too good to be true usually are and strangers that are too nice from the getgo usually want something. In your case what they want is to recruit you then brag about it something along the lines of how they converted the tattooed guy with the piercings, yay us, praise Jehovah. Once they have you baptized the honeymoon period will wear off, believe me.
