When my parents, and sometimes other people talk about something and assume that I'm either, not old enough to know what they're talking about, or that I'm just that absentminded, and assume that I don't know what they're talking about... When I do know what they're talking about... Most the time, it's something I could've gone my whole life without knowing, and I would've been happy. But sometimes it's about me, and people think I can't put two and two together, and figure out that it IS, in fact, about me... And then they get mad when I tell them that I understood every word of what they said. Or, I just keep it to myself, and when they finally get around to telling me themselves, I tell them I already knew... And THEN, they get mad, because it wasn't a surprise...
This is why no one can throw me a surprise party... Because they think I'm to ditzy to comprehend what they're talking about.
I'm smarter than a lot of people give me credit for.
