On the subject of school plays, Ds1 (now 14) was a shepherd for years and years - starting at preschool, right up to around age 7.
It got to the point where I conceded defeat, and made him his very own shepherds smock, with a picture of a woolly sheep on front and back, and a shepherds crook. But tbh - there wasn't much more he could bring to the part...
One evening, we went to the crib service at the local church. We are sitting there awaiting proceedings, when the vicar runs up to us and says "Help! Can we borrow your son for the nativity procession - one of our shepherds has let us down - we've got a spare costume!!"
Ds1 rises wearily out of the pew, turns to me and hisses sotto voce " You know what? I shall be expecting my own border collie for Christmas at this rate!"
When Ds2 started pre-school, they announced to him that HE was to be a shepherd.... cue Ds2 squawking "NOOOOOO - Thats my brothers job - HE'S always the shepherd - I want to be a king or I'm not doing it!" He was so alarmed at following into the family shepherding trade!!
This year, Ds2 (now 8) has been demoted from his original role of narrator, to a sheep! - pmsl! Something to do with his expression, tendency to gaze around distractly, and wave at an imaginary audience I assume, so they've made him a sheep to keep him out of harms way.
He was a bit disconsolate "Never mind son!" I soothe as I sew fur onto white thermals "We've never had a sheep in the family before - we're breaking new ground on the livestock front!"
A sheep!! Still cackling about it now!
