I am a trusting person. End of the day if someone breaks it, i move on and forget about it.
But again things change based on the context, and situation. A bit of common sense and instincts play a role.
Imo there are some bad players, but doesn't mean loose we trust in the society as a whole.
Personally trust is something that let me experiment, and gain from uncharted territories.
From my experience so far travelling to over 2 dozen countries most people are genuinely Good and mind their own business(don't con).
My 2 cents, trust is a 2 way street. It's easier to burn bridges but very hard fostering one.
