It's hard to get to know people sometimes. Sometimes we know good times, sometimes bad. There are those who say go on vacation together and you will get to know better. Live in the same house for a while. There are those who say it will show up on your bad day. In your happy moment, you get to know people with character.
Sometimes you don't know people at all. Whatever you do, you still cannot recognize them. They wear their masks. It's like a masquerade. You don't know who is what.
That's why you have to be open to everything and every danger throughout your life.
