There are many ways to be a good neighbor and here are a few examples. First, whenever you see your neighbor it’s always good smiling and greeting to them! Who would not like to be greeted? Being friendly is one of the examples to be a good neighbor. Being friendly is also another great reason to make more connections/friends with anybody! Especially when you guys literally see/live next to each other. Better being friendly/nice than treating each others like strangers/enemies. It really depends on how you are as a person. Whether you’re a social or an antisocial person. But of course conversation with your neighbors have to come natural. Starts with eye contact then talking! Secondly, as a good neighbor is helping them. For example, if they go onto a vacation they might ask your help? You’re probably wondering what they might ask? Maybe taking out the trash and putting newspapers in their house. As a good neighbor it’s good helping each other. When you go onto a vacation they will return the favor (If they are fair). Lastly, as a good neighbor it’s always great including them with cards/post cards. Such as Christmas cards or etc. Doing this helps you both get to know each other. Such as family names, family members and age. Including each other makes you both feel the friendship going both ways than one. Not just one chasing for another.
