U r welcome. 
Hahaa..Not onli u, me too! I thot tat was some kind of face
expression.. 
It might sound abit harsh..but i agree with giga, yihao..The
prob might not lies with either of u..It's the life of today tat
makes the kids think thy r matured enuf to do like wat thy hav
watched in the television/movie shows..
But the fact is, for a pri-sec sch kid, thy hav seen nothing in
real life yet.
At tat level, u kids r still in a protective giant bubble created
by ur parents. Thy try their best to prevant their kids from the
harsh world, thy do their best not to burst or let anyone burst ur
bubbles..
Instead of thinkin abt somethin irrelevant, e.g relationship, i
suggest u focus on somethin more worthwhile, like ur family &
ur studies.
P/s: & with that, im not particularly targetin at u, yihao..Im
onli doing it generally..
All the best!
