This is apparently a quote from Aristotle "To be a friend to someone you must eat a sack of salt together" (though doing some research, it's not necessarily actually from Aristotle).
Back then, salt would be purchased/stored in bags. It would take a LONG TIME to go through a bag. Thus, you need to spend a lot of time with someone (in other words, go through the whole bag of salt) in order to make friends.
This definitely has the ring of truth for me. But how do you do this, when you're not in school, not working in person, and moved to a new place?
Thoughts?
