First of all, don't bullshit. I can tell a genuine story apart from a fake one.
I am interested in what kind of mischief you have done in the last couple of days, weeks or months. I ask because I am interested in having a window to a real, concrete part of your life. People have stories to tell and some of them are interesting. Post small and big things. It doesn't matter if you stole a candy bar, I want to hear about it. Or talk about anything interesting that has happened to you. Just don't tell me how you trolled someone on the internet. And don't lie because you will only embarrass yourself.
I encourage you to post small things. Reserve big things for when people care.
I do things out of curiosity. If I am in a foul mood I do things out of malice.
I was in a foul mood the other day and got into an argument with two people over small things. The bus driver for trying to close the door before I got in. Some fat guy in the supermarket queue for asking me if I can move my groceries out of the way. The argument with the bus driver lasted the bus trip and the other one didn't last very long. Nobody won the arguments but I felt a bit better at the end of it. I didn't get into a physical fight.
