An unexpected person

My friend called me today. He was one of my friends during my National Service period. I am quite surprising. After we chat for around 30 minutes, i am going to stop our conversation because i need to study for my mid-term exam which will held on 2 more days later. But, my friend claims that, "Why are you so anxious about it? There are still 48 hours for you to complete your studies! " He applied the down-player to make the statement seems less significant to persuade me to continue our conversation.
