First of all I was raised a witness so I know all about it. So just FYI you don't need to "preach" to me about what they believe. My Mom and Dad still go out door to door, but even they seem more apathetic about it then they used to it. It's become more of just something to do together then actually saving people as one person brought up. I remember (and I'm relatively young) when I would go out you tried to talk to every single person you could. Bonus points if they were by themselves. I didn't like it but that was what we did. Now it just seems like they go out of their way to NOT talk to you. This has happened two other times, once in a Wal-Mart parking lot where I even made eye contact and smiled(!) and another time at the bus station, though there are so many people there I could understand how I would get lost in the shuffle.
Personally if it is the case I blame the internet. Religions worst nightmare. This could also be good. The tides have been slowly shifting for awhile so this is just another chink in the armor.
