People who can't take a hint.
Earlier today, I had just gotten up and I wasn't quite feeling 'human' yet. I was sitting with my laptop and a cup of coffee, trying to wake up and watching something on YT, when my brother came over and asked "Who's that? Sounds familiar." I told him who it was, and he said, "Cool, can I watch?"
I told him "No, but it's called *insert video title*, if you want to go look it up."
He said, "That's okay, I'll just listen." and plunked himself down on the couch.
I knew I was grumpy, so I just let it slide, but he kept commenting on what he was hearing. Plus, I could smell his morning breath from there. When I asked him if he could please just go look it up, he got all pouty and said, "Okaaay...I'll leave you alone. Sorry." and trudged out of the room.
How did I go from minding my own business and trying to wake up to being treated like the meanest witch on Earth? I didn't think I was abrupt, or anything, and I didn't tell him that he was gassing me out with his morning breath. Ugh.
