There's a wee touch of selfishness in your gift of a Corona to HER-- You're probably intending to borrow it now and then yourself! And why not? Corona can be loaned with impunity. Your manly touch can't hurt it anymore than can her own dainty fingers.Look at the way she's HOLDING it though, as though she had a muscular disease. Is that what having "dainty fingers" meant? Maybe she's thinking "oh no, machine grease all over my nightgown."
I also like the way that he's staring appreciatively at the Corona, not particularly caring about his wife's flimsy clothing. He is basking in the joy of Christmas gadgetry and wives need not apply.
PS: Only seven keys on the top row? Those really WERE simpler times.
