Harsh greeting, modify

My standard greeting when asked how things are going is, "Good. You?"  After analyzing several facial responses to this, I realize that this sort of greeting is too direct, too harsh.  People believe that I'm being rude or rushing.  I'll modify my initial response to something else to maybe "Oh it's okay, how about you?"

Update:  I limited my greeting today with a new cashier at the Market, but I may have fucked up on that.  I'll merely soften my Good. You? response.

Note to self:  Modify initial response.
