Relationship Squeeze Theorem

     lim         relationship = 0
(t-> 2/14-)

As Valentine’s Day is approached, the more something in a relationship becomes nothing.
Also: something > goldfish > nothing.
Therefore, as it gets closer to Valentine’s Day, something becomes nothing, and thus the relationship becomes equal to a goldfish.
By definition of goldfish, another’s presence is insignificant, and you are playing with yourself.
Therefore, you better get her a Valentine’s Day gift, dearie QED.
