Between Excel marathons and 3 a.m. pitchbook proofreads, some young finance guys find the time to look for romance. But that may not be a good thing in some cases.

Two horror stories stories surfaced in media reports this week, both of which involve young financiers who took intense, possibly overzealous approaches to dating.

The moral of the stories? In dating, as in deal-making, pick your bankers carefully.

The first, a juicy yarn about a blossoming JPMorgan Chase romance gone wrong, was snagged by The Daily Mail in Britain. It features David Gray, whom the paper called a 28-year-old “wealthy American analyst,” and a former colleague, Daniela Rausnitz, 25.

According to The Daily Mail, when Mr. Gray, who had begun seeing Ms. Rausnitz when the two worked together in the firm’s New York office, found out that Ms. Rausnitz had another boyfriend in London, he reacted strongly, giving her “a relentless barrage of visits and messages.”

He deluged her with hundreds of texts, emails and phone calls as he repeatedly flew across the Atlantic to pursue her when their one-year relationship turned sour. Gray used his old key to get into her Chelsea flat, falsely said his sister had died and even claimed he was critically ill in a desperate effort to attract her attention.

The affair ended badly, according to The Daily Mail, when Mr. Gray was arrested by British police on harassment charges and barred from contacting Ms. Rausnitz on any future visits to Britain.

The second story came from Reddit, and involved what its submitter, who identified herself only as Lauren, said was “an investment banker’s cover letter for a second date.” (Not to quibble, but it looks to us like the sender, “Mike,” is more like a money manager for his parents’ money than a bona fide banker.)

Take it away, Mike:

Hi Lauren,

I’m disappointed in you. I’m disappointed that I haven’t gotten a response to my voicemail and text messages.

FYI, I suggest that you keep in mind that emails sound more impersonal, harsher, and are easier to misinterpret than in-person or phone communication. After all, people can’t see someone’s body language or tone of voice in an email. I’m not trying to be harsh, patronizing, or insulting in this email. I’m honest and direct by nature, and I’m going to be that way in this email. By the way, I did a google search, so that’s how I came across your email.

I assume that you no longer want to go out with me. (If you do want to go out with me, then you should let me know.) I suggest that you make a sincere apology to me for giving me mixed signals. I feel led on by you.

Things that happened during our date include, but are not limited to, the following:

-You played with your hair a lot. A woman playing with her hair is a common sign of flirtation. You can even do a google search on it. When a woman plays with her hair, she is preening. I’ve never had a date where a woman played with her hair as much as you did. In addition, it didn’t look like you were playing with your hair out of nervousness.

-We had lots of eye contact during our date. On a per-minute basis, I’ve never had as much eye contact during a date as I did with you.

-You said, “It was nice to meet you.” at the end of our date. A woman could say this statement as a way to show that she isn’t interested in seeing a man again or she could mean what she said–that it was nice to meet you. The statement, by itself, is inconclusive.

-We had a nice conversation over dinner. I don’t think I’m being delusional in saying this statement.

(It goes on. Way on. 1,200 words worth of on. But we’ll spare you.)
