I'm almost ill!

Woke up this morning with a bass/baritone voice and a bunged up nose - oh no, a cold.   Dosed myself up to the eyes and went to do a tour this afternoon.   I was doing quite well until my voice suddenly and completely disappeared causing a great deal of giggling from the pupils, struggled on as it was almost the end of the tour and then to my embarrassment my mobile began to trill from inside my pocket.   'You can't answer it can you Miss, you've lost your voice?' came from one little smart alec.   Kids are so sweet.   However the tour came to an end and the children politely thanked me and went off back to school.   Except for a small number, most of the children I meet from day to day are very well behaved and a credit to their teachers.
