Sleep? What is that?
Bad night: waking up at 3 am to the sound of your dog vomiting.
Worse night: getting up to deal with it and stepping in a cold pile of vomit that you apparently slept through.
Then I got drawn into an argument with someone in a Facebook group. He broke the rules in a way that made it completely obvious that he hadn't read the rules, and when I said "oh for fucks sake, here's a link to the rules", he got super pissy about the fact that I swore. Best part? When one of the admins woke up and saw the post, her exact reaction was "for fuck's sake, not again".
