befriend (someone).

You can only be my friend if I think you're something special. Most are acquaintances.

I understand by the term "friend" here that I know this person very well and had contact since a long time about public threads before getting into PMs.

When knowing this person enough there should be enough trust that you can talk with your friend openly about everything.

And in case this friendship ends after a time there should be at least so much respect and honesty to say "goodbye."

Sadly all this I´ve never found here and I am wondering often if just my standards here are too high. 🤔

I think there's friendly, an acquaintance and then friend ..

I'm a friend and foe

Good friend Bad enemy

Friend 🌹
