Yes, I was on a train with "that mother", and her kids today for two hours.
Sit down, sit down, no you can't have a biscuit, eat your biscuits, stop running, sit down, you are greedy, I said no, get out of the toilet, stop banging on the toilet door, sit down, stop running, I said no juice, let your brother in the toilet, no biscuit, stop running, we are going home, no chocolate, sit down, I will tell Grandma, stop running, sit down, you never behave, I'm phoning Grandma, sit down, wash your hands, don't lock the door, get out of the toilet, greedy boys don't want more biscuits, no juice, stop running.
In an aggressive tone for two hours.
Ugh.
And I went to use the loo which was out of order because said children had been allowed to break it, and no, I don't blame them, I blame the parent, still would pay to be nowhere near them though.
