Not a problem, and yes, children can give answers, we as adults could never think of.
About "細仔", SPCPS seems never mind this one. For sen students, the school always gives good support to her sen students, instead of asking them to leave. So not to mention about "細仔", once I was told by Mrs. Chan that she loved to have a good mix of children in the school and she stressed that you could never see the real potential of a boy until he was in P4.
Recalling the fellow friends of my boy, she is right, no need to give too much pressure to the kids and ourselves.
Good luck to everyone with 2nd interview with Mrs. Chan.
