I'm going to tell an old lady she shouldn't be driving and to fuck off after she tried to scold me and hit my car for being on my phone while parked
That sounds harsh and hurtful. Why would you speak to an older lady like that?
It's the first time I park there, should have checked better
Their behavior does not give you the green light to be harsh or verbally abusive. You should calmly and rationally talk to her in a way to get your point across better.
She's too old to remember so I'm not going to talk to them nicely, I want to fuck that old bitch up.
It's wrong to use harsh and offensive language toward an elderly person. You should treat everyone the same way that you would want to be treated. Consider how you would feel if someone spoke to an older person that you care about the way you spoke to the older lady.
