LOL, no not the same day, I have been saving your 'thumps'....
Still laughing, when I was small, my granny would use her thumb and finger to thump me on the head, when she wanted my attention, or I was up to no good.
She was less than 5 foot and so very hump backed from a life time of very hard work.
I grew to 5'8 and a half inches, so my head was out of reach.
So she would hit my back, at her level, one good thump.
I couldn't understand, when my daughter was about 14, why she suddenly wanted to go and visit my grandmother........
Then I heard her tell a young friend who was with her,
" I just love to see my mother get beat up, by her granny"....
