I have always thought and still think that friendship is synonymous with loyalty, there are friends and acquaintances, those who are in the category of friends are those who are always there, that you can count on them.
When you talk about people we don't know but who seem to have known them before, this has happened to me several times, I believe in reincarnation, possibly these people influenced a previous life and we are in this world again.
I wish you a happy day.
Friendship is no doubt in sync with loyalty as you have said. It's what and who we are loyal to that we can give our time, our effort and even our all. True friendship has no class barrier. I am grateful for the gift of you.
