[ version 1 ]
You cannot tell what someone is like by talking to him or her after just a few minutes. This is generally true. But sometimes you can understand someone you've never seen before by exchanging only a few words. In that case, you feel as if you've known the person for centuries.
[ version 2 ]
Exchanging a few words with someone is not enough to understand his or her character. This is true in most cases. But sometimes just a few minutes' walk with someone enables you to have an overall picture of the person. Cases like that makes you feel as if he or she's been familiar to you for ages.
