It's good to give attention to your partner.
Dave is watching his favorite team's hockey game on TV when his wife interrupts to ask him if he likes what she's wearing.
Dave wants to respond to his wife.
Dave looks at his wife for  a second and tells her that she looks gorgeous in the outfit she's wearing.
Dave waves his hand at his wife without really looking up at hear and tells her that yeah she looks fine.
Dave's wife is extremely happy and feels sexy and tells him to go back to watching the game.
Dave's wife knows he's just saying that and feels like he doesn't care enough about her to take her seriously enough to look away from the TV.
