i ' m not sure what this says about my character

The other day I came home from working and was very tired.  John said something to me and I retorted with a few less than well-formed insult like responses ("I'll show you..." and "your face is..." are the standards).  Apparently I was so tired that they didn't make any sense.  John then proceeded to tell me that I should probably go to bed if I couldn't even form a proper insult.  I posted it on facebook because it was funny...and this is the response I got... I don't think I have ever received such an overwhelming response to a post on facebook.  While I definitely agree with him...because I can almost always form a coherent insult, I'm surprised that so many others agreed too. Maybe I should work on being nicer...or maybe I should just keep being me :o)
