By Commander Data, Starfleet
A tail is quite essential, for your acrobatic talents.
You would not be so agile,
if you lacked it's counterbalance,
and when not being utilized to aid in locomotion,
it often serves to illustrate,
the state of your emotion.
Oh Spot, the complex levels of behavior you display,
connote a fairly well developed cognitive array,
and though you are not sentient, Spot,
and do not comprehend,
I nonetheless consider you,
a true, and valued, friend.
