The only peaceful thing in world is Sleep
There used to be time when we (engineers) used to survive marathon sessions gaming, watching tv series, movies etc. But whenever we wanted to have a peaceful sleep, we could. Single rooms is all required. No roomies, no chattering.
Being is PS, this is one thing which is missed by many people I guess. Random sleeping cycles is met by unstoppable chatter boxes all around the day. Never thought it would come to this point but survival has become essential. Making your own personal space, living with your custom sleep cycle, all what is need to be done.
Sorry roomies and my beloved PS mates if you guys are seeing this, but this is the truth. You guys irritate me a lot, unknowingly. I tried telling you but you guys never listen, not care about it.
