The second clip reminded me of my father, who, in a moment of curiosity, did precisely that with my younger 6 month old sister.
‘She was wailing for your mother! I thought that would quieten her a bit!’ he said to me.
‘So how did it feel? Did it work? Did she keep quiet?’ I asked, myself curious.
‘Aah… I can’t remember anything but the pain. It was excruciating…’ he replied, wrinkling his face in distaste.
I still laugh when I think about it.
