It is an evil, diabolical leaf, and it would doubtless kill us all in our beds given half a chance. Fortunately, we're kept safe by Loki, who is watching it with an intensity generally reserved for vultures waiting for something tasty to expire. Even a veritable Genghis Khan among leafkind must quake before such single-minded scrutiny, and I'm sure that every time he swats the glass in frustration, it about has sap failure.
Occasionally I think "Damn, I wish I could get that much entertainment out of a leaf." But then I write entries like this, and hey, whadya know?
