His son took to the street and started shouting: "Please help us put out a fire at our house!"
After a few moments, a small group of people came out, and the rest acted like they didn't hear the cry for help.
Those who came ate and celebrated.
After the feast, the confused father turned to his son and said to him:
"Who were those people who came to celebrate with us? I hardly knew a single one of them. Where were our friends, relatives, and loved ones?"
The son said, "Those who celebrated were the people who quickly responded to my cry for help. I shouted that there was a fire at our house but said nothing about the celebration. So, those who came to help were also surprised that the fire was your barbeque fire. They deserved to enjoy a great feast and new friendship.
Moral of the story: Not all your friends and relatives are true friends and relatives.
