Like Lucinda and Carolyn say, "Just do it". However, since it is your neighbor, approach whatever you want to discuss in a positive way. Tell them how you feel about it and ask if there is some way you can compromise so you both come out feling good about it. You certainly don't to make the situation worse by getting angry or blaming.
