I have copied out the line about hoping you will not lose it either, into a notebook I have kept since 1987 and which is nearly full.
Thirty one years I cooked dinners in a primary school and the little ones came through that hall like it was the best hour of the day. By year six a fair few had learned to be too old for it, and I watched that happen and said nothing. You are nineteen and still have yours. Thank you for putting it up where people could read it.
