Dear people, please realise that it takes a lot of energy to run your computer, and much more energy to run the computers that run the internet. You are wasting energy worth more than your pitiful self will ever earn for the world.
There is a button called 'logoff' or 'signout' which you can click on while at work or study or pee. I assure you, studying and working can be done without you being online at all. If you have to work from your computer, there is no need to sign in, and if you have gmail to check but don't want to chat, there is an option for that too. There is absolutely no fucking need of you being online when you don't want to chat. Press alt-cltr-del and pour two litres of double distilled water over your computer. Thankyou.
