Bizarre ankles

So, in a strange twist of fate, my sister twisted her ankle about 10 days after I did. She did this without foreknowledge of my ankle. It could have served as a warning for her. Her bruising is identical to the bruising on my foot. The bruising did get worse, as did hers. Her swelling is lower than mine though. She always takes pictures of her injuries, so you can have a gander.
