Last night on a crowded bus, having waited for an age in the cold, only to be met by a cranky driver... small girl gets on with her mum and proceeds to sing "Old MacDonald Had a Farm". She kept checking with mum about what animals she could do ("And on that farm he had some... what did he have mum?...") and what noise they made ("Sheep" "Do they go baa?" "Yes"). As the girl merrily sang away it was hard for anyone to remain in a bad mood, though the girl did spot that she got a response ("are all the people smiling at me?")
Over-dowsed perfume. Really, as Cloud says "have that shat themselves?" Uneccesary and awful for asthmatics...
