I can't do it!

Some people need to understand what they don't know and what I don't know don't make it ok for me to do. I'll say this more clearly. I can't do anything unless I'm taugh how to do it. Other wise I do a crappy job and don't get it done. If the person teaching me how to do something doesn't know themselves, they shouldn't be teaching me! And after there done with there general explanation it doesn't make it so I can so it! I'm ranting on about this because my Mom had me do some mudding a few weeks ago and now she's having me SCRAPE it off a little. But she doesn't know how to do that, so she gave me the tool and gave me a general explanation of sliding it across the mud! I did a cappy job because I didn't know what to do. And she STILL wanted me to keep going!
Ok this rant is over. Sorry I just went on complaining.
Little extra note I've been working on completing Dragon Warriors I on Game Boy Color. I'm ALMOST done but I got pulled away right before the end.
