What we have here...

...is a failure to communicate:

Teacher Dave Barclay flew thousands of miles across the Atlantic to Wales to attend his friend's wedding, only to discover he was a year early.

Barclay, 34, was told about the wedding earlier in the year and assumed it was to take place in 2007.

It was only when he had flown into Cardiff from Toronto, Canada, and rang the bridegroom seeking details of the venue that he discovered the wedding was in 2008.

[...]

The groom, Dave Best, had emailed his friend at the start of the year.

"He just said July the 6th and I assumed it was this year because if you tell the guy July 6th, they're going to think it's this year," Barclay said.

So, these guys are obviously good friends. If they were just casual acquaintances, I doubt Barclay would've flown all the way from Canada to Wales for his buddy's wedding, right? And yet, he never bothered to call Best or even send him an e-mail saying, "Hey, I'm stoked about your wedding! See you in Cardiff next week"? Because that would seem like a good idea. The kind of thing that could, say, keep you from making an unnecessary trans-Atlantic trip.

Dumbass.
