phone call

I received a phone call from my cousin today after my BCT class. He talked about a wedding dinner back in my hometown last weekend, which both of us attended. After chatting for a while about the dinner, he started to talk about me. He told that I need to study hard for my final exam because it's just around the corner which got me to think about himself. And the next thing was, I told back him that, "You ask me to study hard for my finals but you, yourself was terminated by Uniten because you fail all the subject last semester?" I realise that I just used Tu Quoque Fallacy - accuse another person of the same trait or characteristic that person has attributed to you.
