Where Did She Learn That?

Tonight as I answered a few e-mails from customers, Ava (who was supposed to be in bed) played on our desktop computer (which was turned off) and began typing her name. She, of course, typed A-V-A and then asked me what came after the G and R in her middle name. After I helped her with that, I asked if she needed help with our last name. "No, I can do it." And she did. She spelled it out. I had no idea she knew how to spell our last name, I've never taught it to her. I'm sure she's heard me spell it so many times over the phone or in other situations that she memorized it. On a side note, I am shocked by how hard our last name is for people. To me, it's just common sense. Maybe because I speak a little German (our last name is German) or maybe because I'm just anal about spelling. Anyway, back to Ava... she apparently also knows our phone number and address. I'm so impressed by her memorization skills, but this also shows me that she is ALWAYS listening, even when I don't think she is. Better be careful what I say around her... wouldn't want her spilling all my secrets :)
