I'm not going to hang up other peoples clothes from the washing machine
Why are you not going to hang up other peoples clothes?
Because it is not responsibility.
It is understandable not wanting to have to do things for other people especially if you have things going on. However if you ever need a favor from them, they might not help you.
Well, I will be sure to not ask them to do things for me.
It is your choice to not ask anything from them, I respect that, but you may never know that you might need assistance from them for an emergency later in your life. If you behave unneighborly, then you may find yourself not being able to depend on anyone even with such small favors in the future.
