Shortstacks are a very social species, who are quick, to grow attached to those they've (even unwittingly) determined to be their chosen mate for life. A shortstack's mate shouldn't be flippant about making comments that imply long periods of absence in the shortstack's life.
Such comments are known to cause heartache for the poor shortstack, these pains can only be remedied by rigorous applications of "Mating Presses", "I Love You", and "Hand-Holding"
This P.S.A. has been brought to you by the Bureau for the Betterment of Shortstack Health.
