I have three reasons why the nurse who you wanted to talk to may not have responded to you:
1) Nurse is having a rough shift and is mentally exausted and at the time perhaps is having a "duh" moment. :spin:
2) Nurse is having a rough shift and knows in the back of her mind that you probably have bad news and therefore is waiting for you to speak up instead of asking you herself what is wrong. If you don't speak up, then maybe you don't have any bad news to give her. No news is good news.
3) Nurse and her buddy are having an interesting conversation and think that you are simply eavesdropping, or something like that.
Call me a bad nurse if you want, or someone lacking people skills or whatever, but I will stand here and admit that there have been times when I have been the nurse in scenarios 1 and 2. As far as 3... well, I actually tend to be the one who kinda eavesdrops.
Not necessarily because of juicy gossip, I just tend to like to listen to people's conversations, even about mundane things. But I digress...
