my young days (14 to 17 yo) also watch too much three-kindom.
few of us and suay that "have fortune enjoy together, have trouble faced together"
one time parkway eye to eye with another group when start to fight all run different way, slipper also lost while running.
after group back together under one of the HDB flat start to blame one another no "yiqi" from then on, I know everyone talk only.
you never know who you can trust, therefore trust no one. If ever there is one standby you at the moment of time, that would be your brother, but don't try to test during peace time.....不要试人心
