I was labeled as gifted growing up, part of it being I was the smartest kid in the classroom in a lot of my classes. That generally meant that no one really celebrated if I did well academically since it was expected. It was really only a celebration if someone beat me. So I never got used to celebrating what I did since it would just piss people off.
My mom would also usually claim my accomplishments as her own since she raised me and my success was due, in large part, to her.
So I got used to not getting a sense of accomplishment when I accomplished something.
They've had a lot of skirmishes in the past and haven't nuked each other yet.
