Yesterday, less than 2 weeks after getting my PPL, I took my first passenger for a flight. Whilst she (my girlfriend) was not at all nervous (she sat there taking photos of everything... me, the panel, my mum's house way down below) I found that this was a completely new kind of pressure. So much so, that I really had to limit the conversation and concentrate very hard on the checklists. In relation to the original question - yes, I was slightly nervous at the thought of having sole responsibility for nearest and dearest in an aircraft, but once airborne it was all fine.
