Pay Attention To Fake Friends
This will constantly serve as a good reminder of who is genuinely going to be true around us. Experienced it myself and therefore, once bitten twice shy.
Fake friends can be around you right now and they may have ill feelings build up since day one knowing you. They are like crouching tigers, ready to strike when the time is right.
Important lesson in life is to keep them in check, inconspicuously.
