She went to accompany her friend selling ice-cream.
Between that and going to meet her friend at Potong Pasir, did you
or anyone see her? Did she say she was going to continue
selling ice-cream with her friend after that?
The part about selling ice-cream.... Last night, at about 10
plus, I was at my friend's place. Two kids came to the door
to sell ice cream. I didn't have a good look at them cuz both
my friend and I don't buy things from people selling at
doorsteps. But I was wondering to myself, why did they sell
ice-cream door-to-door at such late hours. Moreover, school
term has already started. Aren't these kids supposed to
either rest or do some studies? That's why these two kids
left an impression and the part that you mentioned about selling
ice-cream did ring a bell.
Not sure how this info can help.
