Another one here with a scar in the palm! Mars/Taurus/3rd, in the house it rules.
About an inch long, coming down between index and middle fingers. Was about 5 years old, family outing to the zoo, dad was feeding peanuts to this towering ape/gorilla/simian thing in its barred enclosure, dad gave me one little peanut to do as he did, totally petrified me slowly inched - millimetred - the peanut forward towards the bars.
The THING was standing about 5 feet away staring at me, next thing.......its huge arm lunged-swiped at my hand, little me screamed my lungs out and pulled back my hand, held my hand palm downwards.....then people started shouting, there was blood on the ground!
What followed was even worse, the ambulance, came, we all got to the hospital, and, with 5 people holding me down because I was screaming and struggling, they stitched me without anaesthetic! Gruesome!
I think the Asc is involved too somehow. My Asc would have progressed to 0° Pis (hospitals), squaring 0° Sag MC (zoo, large animals, outdoors). Fortunately it was sextile the natal 3rd Hse Mars, could've been worse.
Well, there IS something Gemini in there after all - the 5s. I was 5 years old, it was 5 feet away, 5 people had to hold me down! Can't remember, but it must have been 5 stitches too!
So, with that story, you all know my Ascendant now.
