This is the tale of one man, two children, and several Samaritans...
David was taking Anya and Callum home on the train yesterday when Anya started to cough. She coughed and coughed and coughed until she started to gag and then... she threw up.
Two men nearby immediately moved out of the vicinity.
Three women immediately came forward to offer help. One even gave David her towel to mop up the mess.
