Well..i say this:
Since strangers are STRANGERS, we don`t know them enough to really judge them. but former friends..

another thing is that seems to me that it says it is actually a bad thing. because strangers-we can imagine good things about them. MOST ppl seem nice at the begining, untill you know them well enough.

i am personally against being judgmental. both about ppl and about reality onm the whole. i ma trying to work on it:not judgin reality.
