One side white one side black ... can boh?

Anyway what to kaji ... just sit in front of school gate or during school assembly can clearly see how many wear black or white. Or just go supermarket or go shoe shop and ask which colour sell more ... like that also have to teach ...

So silly until my daughter's teacher have to ask in the class parents whatsapp group to list down all the students name and what colour of shoe they are wearing ... yeah right, supposed to lighten the teacher's work load by not doing unnecessary stuff ...
