As this sentence says, there is no need to explain. This sentence itself is a free and easy sentence you understand.

I am ugly and my clothes are old, but I am confident! I believe in myself! You can also understand that I am a beggar, but I always walk with my head held high. I'm not afraid of being laughed at. Perhaps, many years ago today, I was a businessman with huge property. Everyone smiled at me when I went to this restaurant for dinner that day. Look at that smile! What a fucking hypocrisy! I passed by here today, and the two waiters are still working there. They saw me smiling, but I didn't make a sound. In fact, my heart is smiling.
