Your grandma was right about it. It doesn’t account for any good to be the cause of someone’s sadness. That is why, at any point in time. If I realize that i have offend or done something wrong to someone somewhere. Once it get to my notice, I will not waste a bit of time than to apologize.

I was not why he was happy, so, shouldn’t make him sad either. It is just as simple. Doing good in front of child and he/she see the good works every time.

He/she will be showing kindness in his life, since the people he live with, or around has that lifestyle.
