No, you are most definitely not being too sensitive. That is a cruel, inappropriate 'joke' that is not in the least bit even remotely funny! I am sorry you have to deal with them and, like adoylelb said, that would be the 'last straw' for me, also. Very cruel and insensitive! If that is his idea of an April Fool's joke, then, in my opinion, it is HE who is the Fool!
