Is it good to have more knowledge about a person?
In general, yes. But sometimes you prefer knowing less.
Especially for a person you admire.
It leaves you room for imagination about this person.
When you get to know he/she more,
There is no doubt the less desirable aspects will start surfacing.
You have to accept the reality that the person you once admired...
...has all these undesirable 'qualities'.
Maybe I am trying to deny reality,
However I think sometimes knowing less might be a better option.
