A dysfunctional relationship can be detected by the behavior of either of the two parties. If the love of a man for a woman is enough to fulfill her desires and grant her happiness, what need is there to supply it with lousy gifts like flowers? The choice could have fallen on something worth using or durable, but the fool buys flowers to her girlfriend as a token of love, oblivious to the fact that he can't satisfy his woman without petty gifts. The flower industry thrives on fools gift flowers to their girlfriends, it is an industry of vanity and conceit for failed men.
