Cabby is a female file cabinet. Cabby is a massive database on wheels. Cabby's a fastidious author of countless files, which seem to contain information about everyone and everything. If it's at all interesting, or even just a plain and simple fact, Cabby wants to know it. Cabby's happy to share her knowledge, as long as you ask her for permission. Or, better yet, if you can tell her something she doesn't already know. Cabby can open her lower cabinet without physically using her arms.
