Employee feels a tinkling of Christmas spirit after bombardment of cutesy Christmas images

During a bombardment of cutesy Christmas images via email, a co-worker found a strange feeling of warmth and happiness had broken through his standard degree of bitterness. The Christmas spirit managed to engage him for a short period of time as co-worker found himself appreciating it and forwarding cutesy email. However, three cutesy Christmas images later, the tired, bored and bitter feelings returned and work went on as usual.
