Hey lil homie Dashainayo,  First of all, It's been more than 10 years than I haven't touched Encyclopedia which was at school library. On the other hand, these stuff are never found on Encylopedia. It's just regular stuff that happens in life. I don't compel myself neither. Then you might be thinking, I am a freaking student that doesn't give shit to studies. You are wrong again. I am a senior in Mech Eng. That answers your question. Well, I hate library though and I don't have shitty time to go my own book so Why would I look for libary books?

Asta la vista
