Dentists, they say that gyms make most of their money in January. Do you make most of your money in December, just before Christmas?

That's a bit of a stretch. I don't believe I resent anyone for their happiness. Life just goes on.

Why would atheists not want people to be happy and why would they not be happy at Christmas?

I honestly think this happens to a lot of people, not just atheists.

I'll wager that churches see the most action in December as people remember their faith for a week or two 🙂
Sweetheart, don't come on this site trying to talk down to people who don't share your faith.

No, but I certainly spend the most then...
