Wetting The Bed lyrics

Why do I wet my bed? Why do I wet my bed every day? And get scolded every day. It's terrible for mother in winter. But I can't help it. My father used to wet his bed when he was small. Still, my father scolds me. Then, I get angry and hit him. My father laughs. Everyday nobody likes me because I wet the bed, yet I'm smiling. I'm smiling all the time.
