How do you end a friendship, or a "friendship" kindly? Online or IRL. Does it matter to you to try at least to be kind as you remove an individual who has been your confidant and friend, for months, or many years? Do you still keep love in your heart for most past friends (I do..)

I remember the few times I wasn't kind.. (when the flowers had wilted and the love I held in my heart turned sour) Many years ago. (long before I joined pc) I don't like that person.
(not about anyone on pc, past or present)
