old post? OP had encountered a tall youth who greeted him/her politely in a loud voice. S/he had thought it was a newbie then realised it was Yunho. He was taller than OP (who is 179) which surprised him.The 2nd shock was his uncommon attitude (his politeness). another poster said s/he was first surprised that even to newbies, (yunho) would greet politely. 2nd surprise was seeing him rehearsing.  First OP said s/he was also surprised by that..s/he could feel (yunho)’s politeness was sincere and not mechanical, done naturally ;;
