When Priyogopal (Subrata's father) goes to visit his student Anupam Roychowdhury to ask for money he is shown having a conversation with Anupam in his office. When he is explaining his circumstance the camera shows him only sitting on a chair with his walking stick. In the very next scene when all the three characters are shown (third one being Anupam's wife ) the top of his walking stick has changed direction. The round bit on top was towards the right before and is turned to the left in the very next scene.
