One must never confuse people who are always around you with people who are always with you.
Even the loveliest rose come with thorns.
Even the simplest path have ditches.
Even the broadest smile hides selfishness.
It’s better if the lovely roses show you their thorns. It’s better if the simple paths warn you of the ditches. It’s better if the smile frowns at you. At least you know, you can trust them.
The first rule to be followed in the real world is that not everyone in this world is your friend!
