what you are saying is totally right and I wish all the people think this way, as there are many who don't respect their parent and never even ask about them. They forget all the things and how their parents sacrifice to grow them up. and a good point that you indicate to is a regret, sometimes things can't be fixed, like those who don't honor their parents and days passed and their parents passed away, what will regret do for them, in case they feel regret.
