I dont know, my brother has terretts and a bunch of shit and he acts the same way. Hes never high. He stands in front of the tv and battles people on yughio that done exist. Hes a dumbass.
When i have friends over he follows them around and they call him don vito. He doesnt get it yet. Hes HUGE like 200 lbs and 11 years old. I had a bunch of friends snort koolaid in front of him once he was so weirded out it was funny as hell. He walks around and makes big noises somtimes. Hes obsessed with allt hat yughio pokemon stuff, you guys have no idea. And if you tell him somthing he'll repeat it for a couple days until you say somthing new that seems like good information to him. Hes seriously so fucked up, hes an example why not to smoke or drink when your pregnet.
Lol its all good, fat people are cool, and your just his sort of idol.. I dont even have a sibling, i wish i did that would be pretty cool.
That just sounds like a normal 12 year old to me. Oh and weed doesn't really effect your abbility to do math, unless you don't understand the concept, and your trying to work from memory of an example. Nor does it effect your ability to program (trust me on both of those)
could be weed...could be acid..who knows... ask him.. and after you do..as his brother give him some advice...
I hear ya man, I used to get high all the time before my CS 2170 + 3130 labs. I swear I can program better/faster when I'm buzzed, but I can't get too stoned or I'm slow. Some days I would get in the lab 45 minutes late and still finish before the people who had been there the whole time.
