Buddhist Cremation Ceremony

Anyone who has been to a Buddhist country has seen that Buddhism is very public and not limited to temples. The monks are out in public collecting food and donations and people get blessed on streets, in markets, wherever. Cremations are part of Buddhism and while they are not advertised and usually take place in Wats, they too are public and very much part of the culture. I think some of us have wondered who might appear at our funeral. Will we be like Jay Gatsby where only his father and Nick appeared, or will it be a huge event? I have also wondered who prays for the homeless or those without families. I am not a religious person, but I have never heard of anyone in a Western country going to a ceremony for someone he or she did not know, let alone a homeless person or a person without a family. Such is not the case in Thailand.
