R has gone out on his first job solo today, as B is finishing off another job elsewhere. In the time-honoured tradition of the AV industry we could have booked them out another twice each this week.
I am sitting at home biting my nails and hoping it will all go well for him - he is technically competent, but flying solo for the first time is always unnerving. B is going to go in with him tomorrow morning to fine-tune things, so he really has nothing to worry about. He still is though :-).
