Joke Type: misunderstanding

A bartender brings a guy a drink and says, “Hey buddy, you look a little down. What’s wrong?”
The guy says, “Well, when my wife left, I felt a little sad in the beginning. Then I got a dog, bought a Harley, and asked out the pretty neighbor next door. Things were definitely looking better.”

“Sounds pretty great,” says the bartender.

And the guy says, “Yeah… but now I’m thinking about what’s gonna happen when my wife comes home from work.”
