In London today with my grown up son on the way to airport.He got on the carriage as I was following him- a woman hurried to get off with her son about 6 or 7- whether it was the heat or too much dinner but he projectile vomited and I was covered- she didn’t say anything to me - probably too stressed or embarrassed .the doors closed and I am standing with sick in my hair, down my jumper, on my trousers and all over my suitcase. The floor was a bit grim as well.My son managed to get some tissues as he was turning green at the stench however some of the passengers were so lovely passing tissues and wet wipes up the carriage. It was just when others got on the next stop and complained about the smell and just looked at me. What a start to my trip.
