I'm going to be defensive about my activity on social media
What are you going to be defensive about?
People keep giving me a hard time about what I'm saying online!
You shouldn't say anything you wouldn't say in person. If you fell you have to hide it maybe you shouldn't say it.
WTF I'm laughing because I can't wait to cause a problem on Facebook.
It's not right to find amusement in being rude with people. How would you feel if they treated you like this? You should get a hobby or something to have fun.
