Tips for a being a great neighbor:
Be mindful of your neighbors’ schedules. If you know your neighbor is heading to or from work, or some other engagement, don’t be hindrance by trapping them in a lengthy conversation.
With the exception of your initial introduction, do not drop by without calling first.
If you are visiting, do not overstay your welcome. Be aware of your neighbors’ behavior and activities and politely excuse yourself when you feel the visit is drawing to a close.
Do not take advantage of your neighbor’s special skills. If your neighbor has expertise in a certain area, you are not entitled to endless consultations and free advice.
Ask for help only when it is necessary and thank neighbor’s appropriately for favors.
