Just curious..

I'm not religious at all, but I don't turn people down when they say "Praying for you" because they can believe in whatever they want and I'm not going to judge. But for people who are religious I was just wondering how many times you actually prayed for someone when you told them you were going too? How many times do you tell someone "I'm praying for you"   And actually do it? Or do you just say it out of curtesy and go along with your day? Just a thought I had and thought I'd ask(:
