Okay, so, someone posted on the blue app about a sequel of this story about their children — specifically their twin boys doing it together. Yes, you read that right. They call it "twincest". Anyway, out of curiosity, I did a little research and learned that it's common for snakes (reptiles) to mate with their siblings as they do not have a familial bond unlike humans. So, I guess it's just them doing nature's work. ┑( ̄Д  ̄)┍
I guess grandma's death represents the ending of Dan's hardships? I don't really know what to feel about this, but I'm alright as long as Dan is happy.
