The bane of existance

I remember a profile picture update from Jason, a buddy of mine on facebook, that I truely feel needs to be mentioned.

The update went as follows:
-"That rooster with its glowing eyes has been the bane of my existance for over a year."

The backstory for this is fairly straightforward in that he used to live in an appartment near Umass, Amherst.  Down the street from his place was a farm that housed a very adventurous rooster who would wander the stretch of road to Jasons yard and "make rooster noises all morning".

This is a picture of the guilty party (the rooster is the one on the left):

Might as well put his update (categorical proposition) into standard form.

quantifier:               that
subject term:           rooster
copula:                    is
predicate term:        the bane of my existance

The copula im not 100% on, and I dont know whether or not leaving out "for over a year" was a good move for the predicate term.

Let me know.
