Meteorological events are currently going on, according to a work colleague.
Your co-worker first made the stunning observation that conditions outside have not remained entirely stable when he noticed that while it was sunny earlier, rain is now falling from the sky.
The colleague can currently be found lurking around the coffee machine in a magnanimous attempt to share his knowledge with as many people as possible. He was last heard opining that the changing conditions make choices about what to wear more difficult than they would otherwise be.
The findings have stunned and divided the workplace. This is the first time that weather has been observed to change over a period of time and has left many in a state of shock, unable to do anything other than share the news with everyone they meet.
