I've slapped a granny
How can you justify slapping an elderly woman?
I've seen how she is and I know that sometimes she deserves it.
There's no excuse for being violent towards an elderly woman. You should seek professional help if you make excuses for violent behavior.
Why would I ever do what you said? I'll slap her again if I need to.
That is horrible that you would do that. It is bad to hurt others especially when they haven't done you no harm. You should treat the elderly with more respect.
