Stolen Apple

I was eating an apple whilst doing my homework.  As I was contemplating something I was holding it in my hand.  Before I could even blink this little thief had stolen it and was attemping a bite or two or three...

When I tried grabbing it back she ran! This is an often occurence, her running I mean.  Anytime she obtains something that she knows she shouldn't have she bolts for safety. (She does this when I tell her I need to change her diaper too)
