Perhaps, I should add my comment to this too, eh? Actually, now reading the choices, I think the word Most of the time...is better than Sometimes. So, think of it that way.
For myself, it's most of the time unless I forget. And actually, I've forgotten, on occasion because I was so hungry. So, I'm with you there on that one, Vamrat - except attacking the waitress part, of course. But, I have been shy too. I also cross my food.
Thanks for everyone's participation. It's been very interesting to share these experiences. Also, after minute thought about crossing ourselves in general....my friend was in Greece, many years ago and travelling with her brother to somewhere. They were in a car. And she crossed herself, at one point. He asked her why she did that and she said she had the urge. Then he told her that the point where she did that, there had been an ancient church which got totally destroy and now there's nothing there, but His Holy Mysteries are always present on the same spot. We certainly feel God's messages when our hearts are open to Him.
