The generation change on 2010 was a biggie for me as well. I only heard about it at a family gathering and the others were discussing it and I was like "Excuse me, can you explain what your talking about?" as I had an usual job at the time and missed the Watchtower and Assembly part where these would have been discussed.
I kinda blew a gassket right then and there saying things like "you have got to be kidding me, really?!!" I had a few chuckles like this is ludicrus (sp?) when I caught myself and stopped as the others there did not find it so amusing, they were looking at me like I was crazy for not believing it. (invasion of the body snatchers kinda feeling) Internally I was thinking " How do any of you REALLY believe this hogwash!!! you have got to be kidding me, this is so obvious that they are making these things up as they go along"
So I ask my wife later why did she not fill me in on this new light and she said that she knew how I always reacted to new light from the WTBTS and did not want to rock my boat as it were.
I do remember having a reaction back around 1995 to the generation change but cannot truly remember what the teaching was prior to that and also what exactly changed about it in that year.
