Torah and Shalom bayis

Rav Dovid Moshe Steinwurzel was an important rabbi dayan and teacher at Bobov in Brooklyn. He was always thinking about Torah. One day he arrived to teach at Bobov and  his students asked why he was carrying a paper bag? He was surprised because he normally did not go around carrying a bag. He looked in it and was shocked- it was full of garbage and he had carried it from his home in Midwood to his class in Boro Park on the bus. He then remembered that just as he was leaving his house his wife and asked him to take out the garbage. He had forgotten about it until he arrived to teach and was asked by his students.
