It is easier to talk to a stranger than people you're close to. That is just the way it is.
there's no chance its gonna come back to bite you in the arse if they don't know you, "we'll always be best friends... you know too much" haha
Once you get to know people, and like them, you care what they think about you. You want them to see you in a good way, so you tend to hold back telling them things that might make them think less of you. With people you don't know, you care less what they think because their judgment or rejection has less power to hurt you.
It's better they find out earlier. You don't want to spend all that time and effort becoming friends with them only to get pissed on later.
not sure why
Because maybe you never will see them again so they say what they want
