A guy I dated for a few weeks in high school was standing at a bus stop when I was driving back to my old home town to visit my parents. I waved at him and he just looked bewildered. So, I messaged him on Facebook just to be nice. It turns out that he had no idea who I was cause he’d been in an accident and a nearly half-year coma.
He somehow woke up with a Scottish accent and had to relearn to walk. His family finally figured out that the Scottish accent was because his ultra Scottish grandma was with him a lot as a baby and I guess that’s what his brain latched onto.
On a brighter note, my ex-wife at the time stood beside me the whole time and no we are back together and closer than we ever were.
