every child is so different it's hard to just put a blanket statement over 'boys' and 'girls'
parenting might have a part in some situations. but also the childs own personality they were born with has alot to do with situations as well.
MY daughter is the one who doesn't listen when i tell her to stay by me. she is the one who keeps going out of the play area at the mall(this last time i think she finally caught onto consequences of not getting to play if she left the area). SHE is the one who keeps doing the same thing i have told her not to or gave her a time out for.
they both run a lot!
there are plenty of boys/males who grow up and never break a bone what so ever. and some girls who are accident prone. i think it just depends on the kids, what they are interested in, and their own body make up.
the peopel who say these types of things are just speaking from their own life experiences and that should be taken into account when you hear things from anyone..lol lol
as far as your nephew. if a child some into my house and touches things i don't let my own kids touch i myself do something about it. gently redirect them and say 'no no no, we don't touch the stove' or what ever the situation is.
to your last statement 'but at least listen to their parents'.. lol lol what child does that all the time? lol no child listens and follows directions ALL THE TIME. now that is a blanket statement that HAS TO be true..HAHAHAHAA..
(only my opinion:-)) )
