I say um all the damn time. I mainly do it because I silently block for fucking ages and I need to let people know I'm still in the conversation. That being said I pull faces when I block now so I'll probably end up killing myself within the next few years. Blocks are one thing, but pulling some fucked up exorcist like face that makes my jaw ache all the damn time; yeah no thanks. Once I've enjoyed some non talking things I want to enjoy, I'm out. ;) And I agree you shouldn't tell your brother. I agree it sounds like you're semi-retarded or something, I hate hearing myself talk; so I don't talk anymore. I'm looking for a job where I can work completely alone. I hate talking; even more so because I pull faces. Sounding mentally disabled I can deal with, looking like it though is another. At least the mentally disabled have the privilege of not being aware of how the may look to others; I'm assuming it never crosses their mind. It crossed mine mind every time though; there's only so much of this bullshit I can if I'm honest.
