What do you think of me telling an elderly lady to shut up in front of her grandkids?
Why would you disrespect an elderly lady in front to her grandkids?
She has been very rude to me.
When you disrespect people, you think very little of them. Talk to her in a polite and kind way so that you show that you respect them as a person.
F*** off I live in my own box.
There is no need to be so aggressive with someone who is elderly. A gentle approach would be fine.
