Sarcastically Small Tree

Our new office manager threw out the company Christmas tree during a summer tidy-out of the office.  I have since been merciless in calling her to account for this crime.  In retaliation she bought me what can only be described as a sarcastically small tree.  To punish this I have decorated it with tinsel (which she hates) and sent her a photo.

This is all part of a perfectly normal and healthy workplace relationship right?
