Never used the internet before?

Let me clue you in. There will be shit talking. There will be toxic people. There will be trolls. There will be foreigners. There isn't an actual way to verify people's age except for their consent of actually saying they're "x" age.

Miscommunication happen, but don't tilt yourself and don't act like a tantrum throwing, egotistical having, blood boiling asshole because you're misinterpreting actions and pings making you misplay.. Don't throw the game out the window because YOU have emotional issues. Your team's tilting you? No, you're tilting yourself by being a brat. Stay calm, play the game and own up to YOUR mistakes. It'll make you better.

TL;DR

Stay calm, don't tilt; Shit happens.
