The blizzard of '15

The friendly supermarket cashier asked the Complete and Total Loser whether he was stocking up for the anticipated severe weather due to hit that night.
"Nah," the Loser said. "It's only going to be a few inches."
"Oh!" said the cashier. "You're so optimistic!" 
The Loser shrugged and smiled.

About three inches fell. 
The Loser's area newspaper ran a photo of some girls sledding on what was mostly grass to go with their story about how the storm was nothing like it was predicted to be. 
This often happens to the Loser when it comes to the weather. He looks at a weather map with care, and just knows. 
So why is it that he can do this yet he never has an idea—even now that he's in his mid 50s—of what to say to a woman?
