They know their self-worth
Loyalty shows and reflects your inner self. And that is why if you meet a loyal person, you will see that they have a good sense of their self-worth and aren’t actually insecure at all. They love themselves and know they deserve loyalty as well.
It’s a gift no doubt to know exactly how you are inside and loyalty brings all of that outside by itself which is truly a blessing.
They don’t require other people’s opinions who tell them how they are. They consider it wrong because their inside is their personal space and only they know who they truly are inside by having a great quality of loyalty.
