SIL is an avid golfer.  He plays two to three times a week.  In fact, this story below indicates just HOW MUCH he loves the game.
Hole In One 

 SIL has been playing for twenty years but has never had a hole-in-one.
As he was blasting away in a sandtrap one day, he voiced the thought.
"I'd give anything to get a hole-in-one."
"Anything?" came a voice from behind. 
He turned to see a grinning, red-clad figure with horns and a tail.

"What did you have in mind?" SIL asked.
"Would you give up half your sex life?"asked the devilish figure.
"Yes, Yes I would." he eplied.
"It's a deal then." and the figure faded from sight.

On the very next hole he did it!
The ball soared from his club in a perfect arc right into the hole for his
first ever hole-in-one.
And amazingly, he aced every other hole that he played the rest of the day!

At the end of the round, the figure in red appeared again.
"Now for our bargain," he said.
"You remember you must give up half your sex life."
SIL  frowned. "That gives me a bit of a problem," he said.
"You're not backing out of this," cried the figure.
"We struck a bargain and you agreed to it."
"Yes, of course. But I do have a problem.
Which half of my sex life do you want ... the thinking or the dreaming?"
JUST KIDDING!  JUST KIDDING!
Seriously, he really does love to play, but green fees are expensive in Dallas.  Every time he plays, it costs him from $40 to $60, depending on the course.
Since he plays at least twice a week and sometimes three times, that adds up to between $400 and $500 a month.  So, Holly has decided that they are going to join a country club, since monthly fees are about that same amount. 
Then Bevan won't have to pay green fees and they can have the other benefits of the club as well.
Makes sense to me. The rest of the family should get to have some fun too.
