addiction: friends real?

what is it about people? Why would someone wait outside a window throwing rocks for almost 2 hours because there was the chance that they might get high. Party foul! Did anyone invite them or did they invite themselves, probably the latter. Is it right or wrong to lie to them and tell them to leave. Sometimes it feels like you’re the bad guy but at the same time your doing what you think is right. Isn’t that ironic. I don’t get it though. Does that make you a bad person? Also what if they find out you were lying then they get all pissy. What then? do you tell them its not your problem? What do they think. Do they secretly despise you. Will they now talk behind your back and tell people you are a bad person, when all you have tried to do for so long was make people happy. But it is not your job to get people high. They need to understand that, but their mind’s won’t allow them too. I hate bitching about this but its god damn addiction rearing its ugly head again.
But since they can’t have coke they’ve moved on just like any other addict. Do you ever have “friends” call you and the first words out of their mouth are, “got any killa?” damn. Is it their business? Wouldn’t you get ahold of them if you wanted to hang out. People just start inviting themselves. They don’t even see that there is a problem and if you confront them about it they get pissed, then what? Whats even more screwed up is that you tell them to leave or that hangin out won’t work out that night and they won’t stop. You tell them your parents are up and you can’t sneak them in and they start saying, “what about the window ill go in the window.” Then you tell them that won’t work and they say the back door the front door. Its like they wont stop till you ignore them for half an hour. Then they finally go away and you feel like shit it shouldn’t work that way, should it?
