Is it normal that i feel uncomfortable around my father?

I'd be interested to know if the people feeling uncomfortable around their dads are male or female. I'm female with both parents long dead but to be honest I always felt that I never measured up to their expectations and wasn't good enough in their eyes and especially with my mother, even into late middle age that sometimes made me feel awkward around her in case I incurred her disapproval.

They were both very critical and judgmental people: nowadays I watch young parents going to the other extreme and raving about their children's quite ordinary accomplishments. This must cause problems when the kids get out into the real world and discover that like most people, they're just ordinary like everyone else. A friend once said that you know you're a grown up when you accept that you're special to those who love you and hopefully to yourself, but to the rest of the world you're just an ordinary person - never forgotten it

I feel exactly the same around my dad. He's a nice and normal guy so I dunno why I'm uncomfortable with him around.

No. I wouldn't have asked otherwise. But if u dint want to that's fine.

I have exactly the same problem, and I feel a little bit too old for it, honestly.
My dad is a great guy, there's nothing wrong with him. But I just feel like he's always waiting to criticize, or tell me I'm doing it wrong, or that he thinks I'm an idiot.
It's not a massive deal, but I think that's where the problem comes from, for me anyway.

Apparently you're supposed to "defeat your father" at some point, as part of growing up (or something..?). I'm sure there's been times I've done this, but the feeling comes back. So maybe I just need to beat the crap out of him once and for all..?(I'm joking)
