Septic tank
If we came across a coffin or a coffin-shaped object in our backyard, the last things we’d do were snap a picture of it and upload it to social media. This Redditor is a braver person than us. He and his friend decided to take a picture of a halfway-buried coffin and ask Reddit what the thing was.
This object is actually a lot more common than you might think. It’s a septic tank, which stores all of the waste that comes gushing out of your bodies after you drink and eat. Septic tanks need to be emptied out once in a while, which is why it’s not buried six feet under.
