How to deal with ragers and/or flamers.

The other day I was in the living room with my little sister (4 years old). She's playing some random game on her iPad, and when she lost she was yelling and was angry. After all the league I've played, it seemed very relatable to some of the people I encounter in solo queue. So as of yesterday, I started imagining the teammates calling me bad and the teammates calling "ff 15" or "open mid" as my sister getting mad at some stupid game. I honestly haven't felt the slightest bit of anger towards my teammates this whole time. Seeing a 4 year old rage out at a game had me rethink how insane most people get when it comes to league. Honestly this has been my best way of dealing with ragers and flamers so far.
