Sir, believe it or not but I like your response. You showed confidence, gave specific examples and did not lose any manners in your response. I dont need to see any proof either. If you have been making such painstaking efforts, and those are actually bearing fruit, then that is really commendable. So many people keep raising demands and requests at various levels but nothing happens so your success based on individual initiative is really remarkable.
Best of luck in your future efforts.
