Two fathers were teaching their children how to behave in shul. One father kept interrupting his davening by pointing out the place in the siddur for his son and telling him to daven. The other father had his son sit next to him and this father davened with concentration without telling his son to daven. Many years later, these children grew up and had children. The first son kept pointing in his son’s siddur and telling him to daven. The second son davened with beautiful concentration and had his son sit next to him to watch how to daven properly.
