[26a top] R’ Yehudah quoting Shmuel: There was an incident where a father was carrying his son on his shoulders, before bringing him to immerse in a Mikvah (ritual bath).
Medrash Tanchuma: A father was carrying his son around on his shoulders all day. The boy was able to reach high fruits on the tree, avoid getting dirty in the mud, and travel the roads with the butterflies and birds alongside him. The son got so caught up in his joy that he forgot about his father, who was holding him up the whole time. Therefore, the father threw him off his shoulders and the little boy got bit by a dog on the ground.
D-E-ep Thoughts: We must always be aware of who is “carrying” us throughout life. Just as in the story of Purim, Hashem mainly works ‘behind the scenes.’ We should never have to be hit with harsh reminders, and always recognize His presence in this world as we see ‘Behind the Mask.’
