I will "evade" the topic of wall thickness for eternity bad manners because discussing anyhing with you rapidly degenerates into a boring contest of you trying to "prove" that you are the only authority on anything and everything about Russia. The truth must be that all of us who live in Russia, visit Russia, or have any thoughts or observations about Russia are stupid, lying, morons. I am surprised that you are so tolerant of our silly discussions. Yet you continue to "evade" answering any questions that would give us insite into your knowledge and authority on Russia.
