These people have a range of tactics and remarks which can be very hurtful. It might be your parents criticizing how you are bringing up your children when your own upbringing was nothing to write home about. It could be an off the cuff remark, which is sly or hurtful, and leaves you feeling wounded.
Sometimes, people make nasty remarks which call into question your own honesty, diligence or ability. Other occasions are when friends fail to deliver on their promises such as not doing you the favour you requested or just forgetting to call you.
These are hurtful tactics that you should not overlook and have to put up with. These friends and family members seem to be more intent on laying mines than displaying warmth, affection and support. That is why you need to get rid of them.
