I'm going to use coffee grounds and human bones to fertilize my garden.
Are you talking about actual bones from humans?
No, I am just playing. They are actually bones from a dead pig.
It is wrong to mistake human for pig bones. You should try to make sure you fertilize your garden properly and not create a possible murder scene.
Tomorrow is the last day of my vacation.
It is fine to use what you need to use for the garden, however saying they were human bones at first was a little alarming. If they were really human bones, then that would be a big red flag and make me think that you were a murderer or something like that.
