While visiting Gibbs, Jack noticed there was nothing in the fridge other then beer.

'This won't do.' She thought. So she decided to do him a favor and do grocery shopping for him.

An hour later

'Jack, what's with all the grocery bags?' Gibbs asked.

'I saw your fridge was empty, so I decided to help you out. And before you say anything, having only beer in the fridge doesn't mean it's not empty!' Jack replied.

'You didn't have to do that.'

'It's what girlfriends do. I got you all the important stuff: Milk, frozen foods, fruits and vegetables, and yes, some extra beer.'

'It's not the cheep stuff, right?' Gibbs asked.

'I'd never do that.' Jack replied, smiling.

As much as Gibbs might have wanted to complain, he liked that she would do something so nice for him.
