Scene from a Coffee Shop

I stopped by "It's a Grind" this afternoon just to grab a cup of coffee and do a little writing when I noticed a mother and her teenage daughter sitting at a table across from each other with their laptops opened back to back. They were arguing about something I couldn't hear and then alternately looking down at their keyboards. It got me thinking that this looked like some kind of high stakes game of "Battleship." As in:

"You're not going out tonight (E-4)." 

"Hit. You're so controlling (H-7)." 

"Miss. That's my job (E-5)." 

"You sunk my battleship. That's just like you, mom!" 

OK, I guess you had to be there...
