Sarcastic or Rude?

Tell me about myself...how do you perceive me?  I really want to know because I'm not quite sure myself.  I wrote that post last week about 10 things you may not know about me but is that how I see myself or how others see me?  I really have no idea.  It's kind of troubling or maybe I'm just trying to ignore the fact that I may not be as lovely as I ought to be.  I'm not looking for accolades here...I'm just very curious.  This curiosity just hit me a little more fuller in the face, I cooked a meal for 100 college students and took a few ladies with me to serve it to them (this was really outside of my comfort range but alas...) anyway, I was in a somewhat happy-go-lucky mood and the Baptist Student Union leader said, "I don't know how to take you".  Ok....a while back I was helping with a wedding reception and another woman helping said, "I don't know if you're being sarcastic or rude".  Whoa, that one hurt!  I wasn't offended by her, I was just really convicted.  Did I change my ways?  Probably, God does that to His children, molds them to be more like Him to which I'm very thankful.  Maybe I have a split personality, sometimes I'm quiet...aren't I?
