On Shabbos, on my way home from shul, my son and I stopped over at the house of the new neighbors I had written about earlier. The Mrs. of the house greeted us at the door. After a pleasant "Good Shabbos," I extended an invitation to them for the following Shabbos. Since her husband was not home yet (my shul lets out very early) she did not accept on the spot. Since my wife passes by her house each day to drop my daughter off at her bus stop and she sees her do this daily, we left it that she and my wife would talk.
Today she and my wife talked. Part of the conversation related to the fact that the Mrs. told my wife that she felt that many in the neighborhood were not very friendly. She commented that people look at you funny if you dress different, or use a different tablecloth, etc. All the while, my wife told me, she was feeling somewhat uncomfortable, considering that we were guilty of just this attitude. The Mrs. of the house also told my wife that she felt that we were among the friendlier families in the neighborhood.
In any event, I guess that means that we're on the right track. And they accepted the invitation.
