Do you mean that your parents spoke only of things inconsequential, or that they were poor conversationalists in general?
I would like to say I can relate, if only a little bit.
My parents and brothers oft would tell me I thought I was smarter than everyone else, despite having never said this. That would be a delusional statement, to say the least. It was as though intelligence was not welcome. It was a nuisance. I was a nuisance.
Suffice it to say "intelligent conversation" was not something I had the luxury of.
And really, I know I can be a bit off-putting. I'm as opinionated as I am blunt with a dark sense of humor, a tongue for sarcasm, and a mind that never stops analyzing even the slightest detail. I can imagine such a child would be a bit tiring.
