Mindfulness On Erev Shabbos
Be especially on the alert on Erev Shabbos. Since the Friday that Adam sinned with his wife, the Satan has been granted special powers to wreak havoc between husband and wife during the late hours of Erev Shabbos. The mature husband and wife will resist any temptation to get angry before Shabbos, reassuring themselves that it is only because of the rush before Shabbos that they are feeling upset in the first place. Fighting is the surest way to chase the Shechina out of the home. It is the quickest route to marital unhappiness.
(Rabbi Moshe Meir Weiss)
