Yes a comment like that when your not feeling your best is hurtful. I would say, don't take it personally what the person said to you, but I know in those moments when thats all we can do it does feel personal. I don't think anyones really boring, perhaps we are drawn to different types of pepole and perhaps ths person hasn't realised that not everyone is out to keep "him/her" happy? Just carry on being kind to you and let the dumb piece of %#@&#! fall in her/his own %#@&#! as they will one day.
