being narrator was rubbish. you didn't get a costume, you didn't get to pretend to have wings, you weren't supposed to join in "Away in a Manger!", If you were shy - nightmare, cos you had to stand up in front of everyone, but if you were extroverted - nightmare, because where, precisely, is the opportunity to do some showing off?
Nobody is looking at you because you aren't doing anything interesting, everyone is listening to you because apart from your own child, the only good thing about nativity plays is the snotty precocious little narrator screwing up the script.
