Religious people

I can not understand some people. Almost always they are very religious but they do strange things at the same time and do not see that.
The latest example is that of a friend of my mother - a woman, who was needed to relocate to the another region, and she did could not take a lot of necessary things, because she needed to leave a free space in her bag for Bible, for her religious literature and icons,
and before her leaving she took her dog to the woods and fixed tied it with ropes to the a tree so it do not chase her...

Another bad unpleasant surprise for me was came from my own friend (who I have known know many years). When we were discussing other countries and travellingm and I said I prefer bus or train to airplanes because my dog have breathing problems and cannot fly, he said it is better to kill the dog than to create such a trouble for travel.

But I am sure they are wrong....
