You have your own life and its nothing to do with religion. tell them straight and firm but be nice.

Developing the ability to say 'no' when appropriate is one of the best life skills anyone can have. Welcome to the site.

Give her the phone number to lyft or uber. To write takes concentration and patients when that gets disrupted can throw you off especially if you are in the middle of a thought.

You are being taken advantage of. They are Toxic. They drain you. I learned to cut these needy people out of my life. You can too.

Fuck that. Sever ties

A. There is no more reason to be proud of your atheism than you are of the color of your skin or your height.
B. Regardless of their religious affiliation, it sounds like your neighbors are selfish assholes. For that reason alone you should stop taking their calls.

I see this all the time... I served on vestry at my church years ago and helped out with a lot of things for parish members and the community. When I was in need, not one of them was there for me. I'm more careful now with my time and where I choose to donate time or money. Luckily now I have neighbors who are there for me to help out when I need it. I help them every chance I get.

There is a religious saying that, "Pride goeth before the fall". Because are an atheist, no such punishing fall awaits you. However, that is not the case for your "Christian" friends. Set some boundaries so that you are in control of what you are truly willing to give. For those times when they have needs that you are unwilling to meet. Offer them empathy and moral support. You may recall the story of Job from past brushes with religious dogma. According to the story, Job is being tested by his God through his various misfortunes. Suggest to them that they are just like Job and let them revel in there ability to measure up to their God's testing. Have fun. But don't be cruel or condescending. This really is their monkey and they need to hang onto it themselves. Be a friend, not an enabler.

Disassociate yourself from these people asap. They will suck you dry, if you let them. Stop watching their kid. You owe them nothing. They do not respect you, they do think they're better. Don't worry about what anyone will think either. It's clear they aren't worried about what you think. Good luck.

Christians are funny that way. They think they are the shit just because they go to church and remember a few scriptures. Otherwise, they're better than you. I call out their bullshit.
