There were two butterflies. One flitted from one flower to another in the garden. The second butterfly came to this garden. The first butterfly got very angry and tried to shoo away the second. He thought it was his garden and so he shooed away the other. A few days later a man caught the first one.
The second one came to that garden and claimed it.
Who is the real owner of that garden then? We claim such stuff in our lives as our own. You are just a traveller here. Remember that!
