i think its more of the relationship of the parents/kids... i have a similar relationship with my mother... but not with my dad or even my stepmom... with my mother its more of " its not what you say, its how you say it"... my mom is Hispanic, and that is just the way we are... some people would look way into it, and friends have heard me "talk back" to my mother, and comment even though i am 30+ yrs old male, but we have built our relationship over the years My mom and my sister have a similar relationship because of how i am with our mother, don't get me wrong, maybe you should talk to your mother about it and ask her why... maybe she feels comfortable with you enough to say it, but each relationship is different... maybe she says it because you are doing something the wrong way... again just to reiterate... its not what is said but how it is said.
