I'm curious if there's an English proverb or saying that has the meaning "you can't have too many friends". The matter is, we have such a saying in Russian ("Друзей много не бывает"). In other words, no matter how many friends you have, it's good to make additional friends.
A line or stanza from a poem will do, if proverbs are few. (0:
The literal translation of the Russian original is
Друзей - (of) Friends (Genitive case)
Много - Many (here, closer to "overmuch")
Не бывает - Does not exist: negative particle "не" + verb "быть" (to be, to exist; cognate with English "to be")
Meaning, "there's no such thing as (too) many friends".
