hmmm. i think your qns is kinda vague, it depends on situation I guess. usually will just listen to what she says and its up to you whether u wanna heed it or not. of cos sometimes you may feel she will be unreasonable, but what they say is for own own good.
lol im 21 and i still listen to my mom, shes strict but at times she can be lenient, just be a good boy and a trustable son and anything can be negotiable ^_^
