My dads excuse is "well your sister doesnt have a desk in her room" Yea but she has a fuking table, what can that not be a desk

I swear- my dad lets my sister do her work and classes in the living room with the tv on, but he sends me to my room when i mention having work (btw dad what ever happened to the no technology in my room rule) and then he just expects me to not sit on my bed or use a blanket or anything, and just sit at my desk doing work- like honestly
