>>29469647There are friends, half-friends, and acquaintances.
Friends are people you meet during your personal life that you share interests, successes and pain together and will be at your side regardless of your place in life.
Half-Friends are people similar to friends, but while you care when they're close, the emotional attachment isn't strong enough to maintain itself if there's a significant 'yab' so to speak or something separates them for an extended period of time.
Acquaintances are people you can tolerate, will go out for a beer with every now and then, but you'll drift apart if one of the two don't put in the effort to maintain the relationship.
Colleagues, unless you actually move in together and start a solid life outside of your work, never become more than Half-Friends. That's what Myth are to each other. They enjoy each others company, laugh, cry, share good moments and bad, but when someone leaves that's it. They'll 'say' they keep in touch, but in reality they don't really and become more like business contacts.
