A grandfather, being a senior citizen himself, has taught his 2 1/2 year old granddaughters to call a female senior citizen as mad! The children call the lady so and looks at the lady longingly. People teach little children bad things and it becomes a habit for them. The same thing will happen if good things are taught.
Look at the English word – HABIT. Remove H, then only A BIT is there. Remove A, then you will get BIT. When you remove B, IT remains. Whatever is taught to small children, it remains with them for their life. So, take care of what you teach them. I have not shared this for people coming from notorious families.
