Gah, it makes my toes curl in total cringe to remember the arrogant self I used to be... So convinced of my rightness. Everybody else wrongness.
One home I went to in FS-- the mom and kids were in the driveway and that month our presentation, which I so studiously memorized, was about Babylon the great, the great harlot. Yes, I actually started speaking about this in front of her little children. Even used the word, harlot. Is anybody cringing with me? Totally horrible to think of it now. The mom, the householder, thankfully put me in my place, said something like, "Oh my god, get out off here! Get away from us!" And it was only then that I realized how I must have sounded.
