Greg could tell from Jack's slumping posture he was about ready to head back, and took that as his cue to swipe the last of the girls' dessert, getting a dual protest.
"Sorry, ladies, time to head back. Uncle Jack's about ready to pass out, and it's very-much past our naptime." The twins looked from Jack, to Greg, and then back to each other, and with a few more signs were positioned back on Jack's lap, ready to wheel him out of the restaurant.
Greg quickly took care of dropping a few bills on the table as payment, before chugging the rest of his wine and making his way to the door.
