For an introductory course , you can resort to Campbell Biology ! Totally helped me in my freshman year . <| sep |> The new OK Go video is unlike anything else I ' ve seen . Quick link for ya <| sep |> Ah , well at any rate , that guy sounds like a total prick . I ' m glad your friend was there to help you out . Don ' t worry about people losing respect for you selling drugs takes guts to do , and violence is an unfortunate reality that comes with the territory at times . In the world of drugs , you win some , you lose some basically . I bet if you asked those people to step in your shoes , to understand the caution and fear you had even before this incident happened then they would probably just bullshit you and try and weasel their way out . Besides , drug dealers shouldn ' t be thought of as hard or bad ass , or anything like that , I think it just leads to more problems than good . And if they lost respect over something like that , then I don ' t think they ' re worth your time either . It ' s rough , but I guess this was a learning experience of sorts ?
