From Merriam-Webster:
1a : one attached to another by affection or esteem
b : acquaintance
2a : one that is not hostile
b : one that is of the same nation, party, or group
The vast majority were 1a. I rather enjoy considering people who are not actively hostile to be friends. It invites all manner of goodness and interest into my life.
You never had 1,386 friends. You had 1,386 friends, acquaintances, colleagues, contacts, associates, and people who you know.
Facebook has bastardized the word "friend" to make people believe they need to collect other people.
