Its a biblical command
Everyone of us have had fathers and mothers at one time.
They have looked after us and cared for us when we were little.
Spent many sleepless and worring nights
They have encouraged us in the right way of life and passed on their wisdom.
So we should honour our father and mother.
They deserve our respect.
A father and mother are there when everyone else would abandon us.
Let them know that you appreciate and respect everything they have done for you.
Let them know it is important to you.
Its important to let parents know that you appreciate them when they are alive because there will come a day that they won't be their anymore and then it will be too late to express how you feel.
Show them your love.
