Do you sense the differentiation between genuine and fake friends?
You can feel the different energy from different group of people.
People with intentions or no intention.
You feel comfortable with people with no intentions even though 1st time meeting. It seems like you know each other for long.
When you meet up with people with intention, you just want to cut the conversation short and run away.
All this is from vibrations.
Be the genuine friend to others with no intention and always ready to help each others.
