What's with all the retards playing at night?

I work night shifts at a retail store and when I go home from work I almost always never have the energy to play League during the day (assuming I don't have other work to do in the house) so I'll just fall asleep and wake up in the middle of the night, and treat it as a normal morning routine.

I would log on to play League and be queued with people who would first pick Nunu and say "If you don't say neck yourself 5 times in chat I'll run it down", teenagers/young adults who are high or drunk AF and would do stupid shit in-game, toxic idiots who would rather flame then play the game, people on HUGE losing streaks playing game after game and many more unused examples.

Honestly, what's wrong with these types of people?
