TRUE STORY
Abe Morgan decided to work on getting along better with a certain neighbor, to whom he felt he wasn’t giving enough respect. Erev Yom Tov, he wrote 60 Maalos about his neighbor, and he learned a Sefer “Kaf Zechus” to inspire him to see only good. Guess what happened? Exactly this Yom Tov, he got into a big argument with this neighbor; something which never happened before. His Rebbe told him not to worry, since this is a common test that Hashem gives to His favorite Ovdim, like Avraham Avinu.
