That is such a sexy gesture, you know.

Curt has an adventurous fling with a work client while rebounding from his wedding day breakup. A sequel to the Bride/Groom duology.

Model Client 1 - A Very Private Meeting - Curt meets his new client and a meeting at her place turns into business of another kind.
Model Client 2 - Mile High to Vegas - Angie takes Curt to Vegas and he enjoys some erotic firsts

A wedding ends with an email. Both sides of the story are told in the Bride/Groom duology:

Wedding Night Blues - A text and an email on his wedding day change Curt's life
A Bride's Awakening - A fling the night before her wedding leads Julia to a fateful decision

Give us a lesson then? :)

If the answer to the problem is 23, then why does doubling that figure not increase the probability to 100 percent?

It's pretty clear (I think) that to have a probability of 1 (or 100%), i.e., to make it absolutely certain that two people will share a birthday, then you need 367 people (invoke the Pigeonhole Principle).

The relationship is quite a complex one, I imagine, and certainly not linear, as you're conjecture would imply. It's actually not a million miles away from the topic of my masters dissertation (look up the Cocktail Party Problem for a flavour of it). Essentially, you can view it as a huge network, and as the number of people increases, the number of connections increases even more quickly, so the probability of witnessing the particular kind of connection you're looking for increases quickly, too.

I don't know. My friend explained it to me and it was double Dutch. I believe as you increase the size of the group of people the odds decrease exponentially, so with 46 people there's better than a 9:1 chance that two people will match. What I can't get my head round is why this works. It's so counter-intuitive.

There's a complete Wikipedia page about this problem, for those interested in the mathematical solution:

And my 'Lush birthday' is May 1st.

Luke D, Feb 26 was the day they decided once calendars were invented, but that is just an estimate.

So, the other day I was talking to my friend and she said, "Danny, how many people do you need to get in a room to have more than a 50-50 chance that two people will share a birthday?"

I was like, "That's a bit random! I don't know, top of my head, 366."

"No!"

"OK, I don't know Ashlie, tell me."

"Twenty three."

"Twenty three!" Bullshit!"

Apparently, it's 23. I don't know how it can be 23, and even when she explained it, I didn't get it. So, I want to test this.


This is how this will work. We'll call this thread our 'room.' Every time someone comes in, you have to introduce yourself with your username and give your date of birth (not the year, I don't need to know how old you are).

Let's get this running for a while and then check the results. I'm sceptical about this, but I kind of want it to work. Please don't 'monitor' the thread and wait for a match, as that will spoil it.

I'll start. My name is DanielleX. My date of birth is 15th March.



You can tell your friend that you don't necessarily have to have 23 people in order to find a matching set of birthdays. I couldn't believe my eyes when I read your post. You may not believe this but it is the truth. I'm HopefullAuthor and my birthday is March 15. By the way Danielle, HAPPY belated birthday. I hope you had a wonderful day.

A close and very dear friend of mine, with a little prodding from me, has recently taken the first giant step to being a published author. I’m sure any of you that are writers will remember how scary it was to submit your first piece. Tempme is a very talented lady, and I’m hoping that now the ice has been broken, there will be a great many more masterpieces coming our way. I’ll consider it a personal favor if you would take a couple of minutes out of your busy schedule and read her heart-felt words. If you are able to give her a vote and leave a few encouraging words, that would be super. To paraphrase Neil Armstrong, ‘This is one small step for Lush readers, one giant leap for Tempme.’

For an absolute guarantee 100% of the time, all you need to do is get 367 people in the same room.


Let me cover your shit in glitter, I can make it gold.
