Defense of the Self

If a stranger enters your property, or come towards you, suspiciously or aggressively, with items that can be used as a weapon (or even without it, in which case, expect it to be concealed)...

Never expect them coming for a tea or a chat with you

Never expect things are going to end well

Expect either FIGHT OR FLIGHT (Malay: LAWAN ATAU LARI), with full caution
