"Happy Friday" is one of my favorite sayings, however, it is not always returned with the same level of enthusiasm as it was intended. Many times I receive a very gruff response of, "I have to WORK tomorrow!" Oops, for me, it's just like saying, "Good morning, hey or howdy!" Those greetings receive an immediate reciprocated response. Happy Friday seems to be over analyzed. It is like when someone says, "How are you?" and the other person goes into detail about how they are not good and why (which happens rarely).
Most people use simple greetings correctly with a reciprocated response.
