Expecting to be abused (physically or verbally) in almost every situation does lead to very apologetic "flinchy" children, who grow into very apologetic "flinchy" adults, who are eager to please, terrified of making an error, and live on their nerves..
I know, because I'm one of them - I tried very hard as a child to be "good", but could never be quite "good" enough. It's only recently that I have stopped apologising for things beyond my control (eg the weather).
I suspect that there are a lot of us about.
