My neighbor wants me to fix the loud walking sounds I make, but I am going to tell them that I make no promises.
Can you tell me why you're going to do this?
They don't deserve any type of promises.
That's not very neighborly of you. You shouldn't take your neighbor's noise complaints lightly, rather you should be friendly towards them so they'll be nice to you, too.
I do want good neighbors that are nice to me and always want to communicate with me.
If you want your neighbors to be friendly and communicate with you then you need to be respectful towards them, and that includes taking their noise complaints seriously. How would you feel if the person above you was being loud constantly?
