Got a couple.
Aged about 6, walking home from school balancing on a low brick wall and slipped off - legs either side of the wall. Grazes from knees upwards on both thighs. Never walked along a brick wall again.
Aged about 8, messing about with my flask and unscrewed the bottom of it from the outer casing (nope, I don’t know why either!) didn’t realise the glass inside would fall out and spill boiling drink all over my leg - cue burnt inner thigh and, because I was wearing the most fetching 1970’s skirt with a sort of candle wick pattern, it looked like zebra stripes but pink scalded skin and blisters in lines!!
Aged about 14, making hot chocolate for me and my brother. Lit a match to light gas cooker and, as I did so, a spark jumped into the slightly open box, ignited the whole box in my hand. Ended up in A&E, hand burnt and treatment involved it being slathered in a particular burn cream called Flammazine and tied in a plastic bag to stop it drying out. Waslike that for 4 weeks while it recovered. Now got a difference of over an inch in hand span compared with other hand!!
Most recently, about 4 1/2 years ago, caught myself near my eyebrow with the corner of the car door as I opened it to get in car. By the time I got to where I was going (less than 10 minutes later) had a lump the size of a duck egg over my eye, the start of a black eye and a pounding headache. Took a lot to convince family, friends, colleagues and clients that my then newish DP (now DH) hadn’t bashed me!! Took about a month to go back to normal but still aches at times!!
