hey, first oblivious has two meanings , the first is some1 who is forgetful , forgets alot and the second is like everyone has said , lacking consciousness , unmindful
and for the second debate all what i can say is that you should have got her , she still a beginner as me and its either she doesnt know that we use the modal would for being nice or she just forgot about that and she thought using please indicates her niceness in asking , iam an english student at college and i my self sometimes forget using it and juts say please and that's why we aren't called natives because we make mistakes such a like without meanign them and we are here asking you gently to teach us , thank you
