My scatteredness. I don't know if it due to being on drugs, taking lots of drugs in my life, or not having drugs (or enough drugs) but sometimes it can be extremely diffcult for me to pay attention to quite direct & simple things. Like when some1 is talking to me, i can veer off into oblivion and generally forget what was said, or pull out a point on the topic, yet not remember what the hell the topic was!!!
I also tend to forget things, have a struggle with maintaining moderation (with most things), have a withdrawing and sullen personality and smoking cigarettes.
Although smoking cigarettes can be contested as a personality trait, i see it as a part so I wish i could change it.
Apart from that, excluding all of the above, the rest of me is great, i swear!!!!!!!!!!!!!!!!!!
(i'm also a horrible liar)
