When I was in high school my family was sitting around the table having dinner and I was talking to some of my siblings while my dad was watching the news. My dad, trying get me to be quiet so he could hear the news, said "Maybe if you listened you'd do better at school."
Firstly I'd like to point out the irony... him telling me I needed to listen, so he could get me to be quiet. So he could watch the news rather than join in the conversation with his family, as usual.
Secondly, if he listened to me, if he'd been paying attention to me at the time, he'd have known that I was doing badly at school because if anything I listened too well: I was always learning everything in my classes before everyone else, to the extent that they'd become boring... that's why I didn't put much effort in.
Well, I think he's grown some now... he has a much better relationship with all of us, including me. Guess he took his own advice finally and started listening.
