NO, its a passive aggressive thing for me. I could underline the materials in 5 mins if I wanted to but I want people to see how uninterested I am. I don't even have the gumption to do a counter study to try to correct teachings. Probably haven't commented in a couple of years.
Interestingly enough, I was one who tried to do a good job in studying. I would look up info not only in the WT pubs but outside sources like eSword. I would often comment on how other translations rendered verses (of course with a WT spin). What amazes me is that I would often read contrary info and just dismiss it outright! I recall preparing for the Daniel bookstudy and looking up historical info on 607 etc and just thinking the secular sources were completely wrong. It goes to show you that people will just dismiss the truth about the truth until they are ready to accept.
My wife also doesn't prepare. I wouldn't say she ever really studied, just underlined and wrote scriptures down. But she hasn't done that for a while.
