I noticed that, too. The witlesses boast that they get gifts all the time, and that they are not missing Christmas. However, I notice that they rarely get anything of value.
I have seen this even in families that I never saw before. I went to a Grand Boasting Session once, and there were three children. Seems they had a toy binoculars from a Happy Meal (and you know how crappy the optics in those things are--stamped plastic, optical and chromatic distortion so bad I couldn't see a damn thing with them that I couldn't without them). The kids were enthralled with this toy--which is pretty blatant evidence that presents in that household were so rare that the children have little to play with. I felt bad enough for them (the youngest was only 6), that I went to a mall to search for something they could actually enjoy--and, for around $5, I found a calculator that they could have fun with. Which was probably more than they got all year for fun.
Another, right in my own former congregation, was a family including 2 children and a hounder father. The mother was born in the cancer. I have been in their dump (it is a dump, since everything in it was crap quality), and noticed how few toys they have. They had a Nintendo game system (with a grand total of maybe 8 games, including the ones that came with the unit), a few dolls, a Merlin (a phone-like device that you play games with the numbers), and relatively limited stuff to draw with. They were home-schooled, so I would expect the art supplies. This was about average for what the children have--very little.
Yet another was the lead hounder when I first went into the cancer. His family had practically zilch--supplies for boasting sessions and field circus were bountiful, but toys were not. They didn't even have a damn TV or radio! Yet, they had the means to play Kingdumb sxxx in their car. They had plenty when it came to theocraptic items, but nothing when it came to entertainment. One would think everyone in the place was in their 90s and 100s by looking at it. Even my grandmother had more in the way of entertainment, despite my grandfather having had a stroke that makes him sensitive to noise, than this family had!
Yes, those children are missing out on a lot by not celebrating holidays.
