If he wants compassion he should go to his mother. I'm sorry but I got really pissed off from personal things so in probably gonna be angry for a few more posts.
Then forget off. Seriously, if you're angry over something then it's usually reasonable to go and get it out of your system
before interacting with other people. Just because you're on the internet doesn't mean you have the right to take out your anger on someone else; just because you're on the internet doesn't mean you shouldn't adhere to common social etiquette.
This is something that seriously annoys me. What makes people think that they can get away with being an starfish just because they're "in a bad mood"? You can't; you're still an starfish, the only difference is that you're a grumpy starfish.
