'Interesting' sights in the mrt

Monday, when I stepped into the mrt at city hall station, there was this girl with her mum & brother sitting in front of me, she was drinking coke (I think) from mcdonalds…one SMRT service officer came in to tell her no drinking in the mrt…she immediately stopped & passed the drink to her mum & asked her to keep…however, the mum started to drink the coke…n the girl ‘shouted’, “cannot drink, cannot drink, just now that person said cannot drink!”…then the mum said, “make sure it doesn’t topple over” while she tried to keep it in her bag…

I was thinking…who needs more education? The mum or the daughter?

Meanwhile, the son was playing with a ball (with a string / spring attached), throwing it out and catching it back…without considering whether it will hit anyone standing…
