Marsden is Here

True, pranking falls into that category of "I really do not understand or like this form of behaviour but I can accept that others do and that it is all right in a mutually consensual environment."

On a personal note I get the unhappy feeling from various conversations that everyone else in the office I have recently started working in believes the office to be a mutually consensual environment for some level of pranking - although this hasn't been put to the test with me yet.
