Friday the 13th

Yesterday was Friday the 13th, which makes the date 13/5/05. Now, I'm not superstitious and I don't really believe that this day is unlucky. I was on call and I just reached home an hour ago. Had a shower and thought I'll update my blog before going out. Yup, I got to sleep at 12+ am last night. I'm going to relate a weird incident to which I still don't have an explanation.

1 of my duties when on call is to prepare for the next day's cases and on Friday, we'll prepare for Monday's cases. So I went into the theatre to get some sticky tape. The moment I step in, the anasthetist told me that Sister E is on the phone. My colleagues were busy getting ready for their case so I answered the phone. Sister E told me to get a box of hernia mesh, 1 laproscopic, 1 normal and meet her 'outside'. She said she wanted to talk to me. So I did what she said and got the boxes out. I thought she meant outside that particular theatre. But when I went out, there was nobody around. So I thought I misinterpret it, that she meant outside the theatre. So I went to Recovery and Reception but still nada. My colleague then help me page for Sister E both through the PA system and through pager. There was no answer. What can I do right? So I went back to the corridor to prepare my cases. When I saw other Sisters in my discipline, I told them what happened. Their answer was the same. Sister E was on leave and she didn't come into theatre. So who spoke to me on the phone?
