Holiday Cards that are Printed with No Personal Message or Signed Name

I get Christmas cards from people who don't sign their name or write any personal note. They just stick their printed cards in envelopes and send them along. I guess it's better than no card at all, but really...not even my name or a signature. Am I wrong, Dervish?

I enjoy getting your holiday greeting
But you write nothing, the point, it's defeating
Is it such effort to sign
Your name and mine, or one line
Just one simple word? I don't expect Keating
