I just say thank you and change the subject

I say it is your time, I really do not care what you do.

I thank them. Prayer has a net benefit. It doesn't do squat for those being prayed about, but it makes the one doing the praying feel good. So, on aggregate, mankind benefits from somebody praying.

I'd say "thank you" in a polite manner and with a smile

Thank you. that would be my answer.

I just Thank them and move on

hi how are you god bless you

Tell them to f#@k off,it is a wicked thing to say to someone.as if you are evil for not believing in a supernatural dictator that can't be justified or proven,ask them to leave you out of conversations with imaginary friends

Depends on how well I know them, but usually it's a thanks but don't waste that on me.

It depends on context. It can be an expression of honest sympathy, but more often than not, the specific words "I'll pray for you" is the passive/aggressive Christian equivalent of "Fuck you". Ie; If I tell someone, "I'm going in for surgery tomorrow" and they say "I'll pray for you", I just say thanks. If they ask me if I believe in God, and I tell them I don't, that's the passive/aggressive Fuck you, to which I'll say something snappy.

If they're trying to be kind then I just say thank you.

If they're trying to be condescending or give a backhanded insult (usually about my lifestyle) then I tell them that unless they're without sin themselves they shouldn't be casting any stones so they can shove their prayers up their ass.

Say thank you and move on. Most don't mean any harm by it and if they do, it's their time to waste.

Depending on the context. Sometimes a a random unknowing person says itand I agree. However when others who know I'm not religious do it I take it out spite and usually my backlash is fairly violative.

I just say "Thank you, but you can just give me a hug instead."

I tell them they can pray all they want but praying to their imaginary sky daddy isn't going to do anything and I didn't need no help from a non-existent being. That is if they are being rude or smartasses about it or something. Like "Oh, you are such a troubled person for thinking this. I will pray for you". But if an argument didn't occur for them to say that, and they are saying it to be nice because something bad happens, I'll either say it's not needed but thanks, or just say thanks.

Please, just send money. (Sounds like the tactic the religious use!)

You must enjoy talking to yourself. I've heard that psychologists can be good listeners...

It creeps me out. lol

I also feel like telling them -- they're usually Christians -- that it's contrary to the teachings of Jesus. It's about vanity, but they don't seem to care about that commandment.

Depends on who is saying it, why they are saying it, the location, the audience, & many other factors.
Often asking questions which require thinking is the best response.

My response to that most of the time is, thank you. I ignore the statement, "I will pray for you," I would rather just interpreted it, in my mind as I hope things get better for you. However, if they are saying after finding out I'm an atheist I will pray for you, I say, "Do what you will, nobody will stop you, but nobody is listening to you either."

If they're being rude, I tell them no thank you. If not, I just let it go. If they believe that their prayers will help, and they care enough about me to do the thing they think will help the most, it's kind of nice. My thinking it's BS is almost beside the point...

Normally I just thank them. In my own personal experience it's rarely intended as something negative.

"Thanks."

I usually thank them, but make sure they understand I do not believe in prayers, especially in someone else praying for me. As for praying in general, I tend to believe that, if kept private, it leads to self-inspection, self-encouragement, and a personal mantra that helps people (of all religions) regain their selfonfidence and do achieve their personal goals.

I don't say anything. It makes me a bit uncomfortable but I know that is a common reaction.
