Hi - my husband and I are living in our home for eight years. We like our neighbors but we don't feel like we know all of them. We have discussed having a neighborhood party but don't know how to do this since we don't know all the neighbors by name. Should we put an invitation in every mailbox and address it to 'Hi Neighbor'? Also, we rather have it in the evening and without children, is there a way to say that nicely? We thought if it said 'cocktail party' and is held at 7:30 PM then people should know not to bring their kids. Am I assuming too much?
