The child is expressing its sentiments in the song:
The child is pleading her mother to take a day off for me and be with me.
You alone are my brother and sister also.
Dad also goes to office and comes by 7.00 p.m.
I have nobody to play with. (No siblings) . Why do you want to go to office?
You also leave me at the creche and go to the office.
I don't want toys nor I want sweets.
Still, If you leave me and go, I won't wave (say bye) at you from the window.
