What is the highest courtesy you have ever met?

I think the highest courtesy I received should be that year. The mountain road was difficult to walk. I was so tired that I stopped to drink mineral water after climbing. Always teasing me, drink less water, there is no ladies' room on the mountain. Finally climbed to the top in a panic. 12 the soldiers waved bright ribbons, shouted welcome, warmly welcomed, and lined up to meet us. I was so excited by this unexpected grand scene that I held the hands of those lovely soldiers and didn't know what to say at the moment. At this time, Lao Yu stabbed me and pointed to the direction of the barracks for me to see. A slogan was posted there, warmly welcoming Comrade Meng Zhi to come and guide. I think this should be the highest courtesy.
