Nice entry my friend, well done. You have written in detail about the role language plays in a small setting like family and in a larger society.
I enjoyed reading your post. I am Yoruba too and you can agree with me when I say Yoruba is a very interesting and detailed language. It is not to be spoken anyhow as almost every variation one makes has different meaning and one must speak and listen carefully to avoid miscommunication.

Well done and goodluck in the contest bro.
