I can definitely relate to this. Earlier today, my dad asked me to fetch him a paper towel. I wasn't quite sure from his tone of voice whether he was joking or not (he does that a lot), and I was terrified that he was. I was so afraid that I'd walk in there holding a paper towel in my hand and be mocked for having taken him seriously. I got so upset over it, it was just silly.
I'm fifteen and I'm also homeschooled. I didn't expect to run into any other homeschoolers on this forum.
