The aniversary of being friends with a person.

NOTE: This only works if you remember the exact date you met

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.

A long lasting friendship between two friends on the day they met. It is like an anniversary, but you add the word friend to it.
