Well guys, I've noticed that many of of y'all are getting really disturbed by the kind of content the user, 'whoeven' is posting. It's kind of funny as it teaches us a life lesson that we all are gonna sooner or later learn on our own. This world is filled with an immense number of people coming from every single background possible. There are people who will warm our heart, inspire us, and leave an everlasting impression on us. On the other hand, there are an equal amount of psychopaths, perverts, and pedophiles who are gonna batter us down with insults, assaults, and negativity. The tough part is making it through. But we're determined, smart, and hardworking people and we will show our level of maturity by not going down to the same level. I'm not trying to preach or be philosophical. It's just disheartening to see the amount of people disturbed by this. Remember, in a couple of years you're gonna live the life you dreamed about and make your family, most importantly, yourself proud. So don't waste you're time or energy on a guy who's probably gonna spend the rest of his lifetime in his parent's basement. He's probably gonna post some kind of sick drawing or picture to this as well, but  'whoeven', I think I speak for everyone when I say this...... We are absolutely unfazed. 

All the best for the Chem exam lads.
