My dad spends most of his days in his bedroom and instead of trying to talk through walls, I go to his door. If I go in there to try to have a civil discussion all he says is "whatever" and goes back to his computer. Trying to talk to him when he is on facebook is impossible. If I try to ask his knowledge he just blow it off or yell "why would I care? it's been too long. When he does talk to me it is to try to tell me how to do things or what to do, never asking, just stating, and never a thanks.
This has brought me to a point that I would like to be able to talk to him, but get depressed just thinking about it and am to a point that i spend most of my time outside
