A/N

Quick fluff ficlet, written because I wanted to shake off the worst unhappy from Old Wounds for a while. This is set in the same universe as my other shorter fics "Loved Ones", "Cookies" and "Waiting Up". Established JJ/Blake.

Definitely not to be taken seriously. :P

"Fifty," Alex said, mostly to herself.

"What's that?" JJ asked as she put on her sleepwear and climbed into bed.

"My age, in two weeks," Alex muttered and turned the page in the novel she was reading. "Crazy. I mean, I've always been mature, but…"

JJ snorted.

"Right. You were so mature when you turned the garden hose on me when I was asleep in the backyard. Or when you tried to say 'popcorn' and said it wrong and ended up laughing for two hours straight."

"I was very, very tired that time, I would have laughed at anything," Alex defended herself.

"You weren't tired, it was 2 pm on a Sunday!" JJ objected, grinning broadly. "Oh face it, you're no more mature than anyone else in this household, and that includes an eight-year-old boy."

"I hope you think I'm more mature than Henry," Alex said, but she too was grinning.

"Yeah, I don't know who's more entertained by the fart jokes in the 'Despicable Me'-movies, you or him."

"Listen to you, as if you don't try to burp words when you drink beer, like some teenager."

"What do you mean try?"

"I mean you fail at it."

"Alex Blake, you take that back!"

"Not a chance."

JJ grabbed her pillow and held it up.

"I have a pillow, and I'm not afraid to use it…oooff!"

"I have a pillow too," Alex replied sweetly and ducked when JJ tried to get her back for smacking her in the face with it. "Don't mess with me, I'm stronger than you."

"What fantasy world do you live in?" JJ replied and tackled her. Alex rolled over on top and straddled her instead.

"It would appear that I live in the real one."

JJ looked up at her with a smug grin, reached out and tickled Alex in the ribs. The result was immediate; it was like folding a Swiss army knife. A giggling Swiss army knife.

"You don't play fair," Alex gasped and tossed the pillow at JJ again.

"Neither do you," JJ replied, but instead of wrestling Alex down and tickle her until she admitted total defeat, she crawled up close and kissed her. Alex responded eagerly.

"I think we're equally immature," she concluded and wrapped her arms around JJ.

"Probably. It's a good thing nobody else knows how ridiculous we can be in private."

"Oh God, yes."
