Our son takes attendance at dinner now. I've been marked absent three days running

My partner teaches, and somewhere along the way our son picked up the whole routine. Every night at dinner he reads out names from a notebook. Amma, akka, paati when she's visiting, me. You have to answer 'present sir'. Release days at the office mean I've been home after 9 all week, so I'm absent three days running. Yesterday he wrote in the margin: 'appa absent again, inform parent' 😂 I have been informed.
