@jacob: Lol, hat's what my mom does xD I tell her she's told me something, but once she starts her story, she has to finish it.... so she can repeat herself multiple times even over one evening x.x
My dad forgets if he's told me things, but he actually understands the communicate that is "you've told me that before" xD
About people not listening, for me it's that I rarely ever speak up in bigger groups (above 3 people, including myself) so when I speak up, usually it's too quiet so people just don't hear me, but if they hear me... "WHOA! YOU CAN SPEAK?! OAO" Srsly? Yes, I can, but you're a bunch of idiots so I don't dignify you with the melody of my voice

(that's my thoughts in high school and earlier XD and I think an actual event...)
