Dear Neighbor,

If you spent as much time on your lonely, neglected dog as you do on your love life, he wouldn't be such a neurotic, anxious mess.  You destroyed his confidence, energy and personality, most likely damaged for life.

You are disgusting.

SINCERELY,
Neighbor

P.S.
you call yourself a dog trainer?  You bring shame to the honor and make the rest look stupid.
I dislike you immensely.
