Yup, there's a lot of preparation stuff goes on..and they chatter to each other too of course...
Did I ever tell you that years back, when I worked for the heart chaps, they told me that every one of their secretaries had to watch an open heart operation, so they'd know what went on etc....Well, I took a deep breath and plunged in, when the time came...scared shitless I was...All the staff were so kind though, so relaxed and in control of everything...piped music was playing in the background too...
Afterwards, when that particular patient came to see me I told him I'd been there, and he beamed at me, said "I was there too!"...bless him..
When he'd gone though the cardiologist let slip they'd been pulling me leg when they said about watching the operation, but they thought they'd see how far along with it I went.....
