Fantastic bit of thinking there countrigal !!!
I wonder if this umbrella drew in some comments as it is not the norm to see one in the office !!
I now have a small desk fan and it certainly helps me feel a lot cooler. Have had no negative comments from anyone so obviously my little flow of cool air does not make them feel cold. If I see someone sitting there with a bobble hat and scarf on then maybe it does but they don't want to complain

Guess it is all about trying to find a happy medium whatever the problem is. Me with my fan and countrigal with her umbrella.
