Luckily ive not had it happen with my daughter, but my mum has with my daughter as she takes her on a bus..... Apparently there was an old man falling asleep on the bus, and my daughter very loudly says "nanny, why is that man asleep on the bus!" the old man turned around and said "I cant help myself, its because im old" and smiles at her, Leah (my daughter) replies... "Well dont worry, you havent got long left"

If it was me...... id be jumping out the emergency exit
