Just a little bird.. And a big world\ I want attention, but all I get is a seed

The Grandpa watches me.. but he knows more than anyone can comprehend

Why shall he care.. He is in his last days... and when he is gone.. Im Just a little bird.. In a big world\

From a egg to a flying creature.. to a featherd flying rag
