Yes, chosing a "NO" is one the greatest challenges many people especially young men and women are faced with today. Even when that is the best answer or solution to the issue at hand, it just seems "unpronounceable" for the fear of what could come next. I agree with you to "Say No" when you mean to say No.

This reminds me of our primary school song:

"Wherever you go, (go go-go go)
Wherever you be, (sisi eko)
Doo not say "Yes' when you mean to say "No" ( Baba Ibadan) lolz
