(this was the scene in my office this morning:)
Observe how the male of the species will gather and deposit his dirty laundry (Fig.A) on the computer chair of the female.
Often this is a sign of aggression towards the female's other pastime (Fig. B).
It is also probable that the male was provoked by the presence of another, younger Alpha male (Fig. C).
Now observe the female's higher-functioning brain, and her ability to procure a second chair (Fig. D), thus leaving the male's laundry aside.
Finally, having accomplished all her tasks, the female will then travel to the male's workspace and leave a mark of her own.
