Second Day of Rosh Hashanah

I went to the Kotel again in the morning for the second day of Rosh Hashanah. I did the same routine as the day before. When leaving the Kotel a guy stopped me and asked me if wanted to join a Soodah. I asked him what a Soodah was. He explained it is a feast, which is different from a meal. A meal is to eat but a feast is to commemorate and celebrate and food is the mode to do that. I liked that explanation. I ended up talking to this guy for 1.5 hours. He was born in Brooklyn but lives in Israel. He seems about my age. He told me how he is homeless and mentally ill. He gets 4,000 sheckels from the government each month but spends it all in a day. He goes around begging for money. I listened to his story. He started saying how flat concrete is terrible and destroys the human body and how it's best to walk barefoot in the woods. He also said I should buy a tent and live in the forest to save money. He had interesting ideas and I tried to listen to him openly but after 1.5 hours of talking it was clear he was mentally ill. He said he had mental illness but didn't specify what.
