You know I once got in "trouble" at a job I had for about 12 years because two of the women I worked in an office with were offended that I didn't say "Good Morning". I'm NOT a morning person so they would be all cheery and happy and when they would say Good Morning to me, I would just barely say 'Hey'.. I worked there like I said ,12 years, and EVERYONE knew I was not a morning person.. but those 2 women out of the 6 women that worked with me in that office decided I needed to be a morning person like them.
Boy did I go off when my supervisor tried to MAKE me say Good Morning. Nope Nope Nope.  I'm a talker and get along with most everyone once I get passed the morning hours lol but that just really upset me that they were soooo offended I didn't respond exactly how they thought I should.....
