it’s all good

when you’re disappointed, but you’re too sad to speak up about something that has been on your mind. it’s not “all good”. it’s “all bad”. here’s an example: a person said they would call you in 10 mins, so you tell them to tell you when you’re about to call them. they don’t end up telling you when they’re going to call. so you don’t get the notification. and then once you see that they are in a call with someone else in the group chat, you think to yourself... “wow okay.”

Although All good is used as a reassurance word, It can also be used as a way of replying to "Thank You"

Everything is sanguine. Generally a reassurance, rather than an independant statement.

A polite way of saying it's okay, usually in a cool/caring manner.

Despite any possible doubt, everything's cool.

Means nothing is bad.

Used in an optimistic sense to show the lightheartedness of something.

Just like saying it is ok. When someone says sorry it would be relevant to use this phrase
