interesting. I dont know what contradiction you are talking about.
I don’t have to defin ‘is’ and I don’t have to define ‘know’ in this case.
what in the world was the first question?
you cannot use other peoples stuff without permission.
if you are not sure if you have permission, you also cant use it.
you can not logically say the following:
This object belongs to a member of my family.
members of family are not makpid (or shouldn’t be makpid )on each other.
Ergo
I have permission to use it.
Which part of no don’t you understand.
over and out.
