سؤال ارجو من العملقة الرد مع تضيح الفرق بين

[mskmidomidomsk]

i think both have the same answer
you need to change your attitude , don't you?
you need my help , don't you?
needn't will be used if the auxiliary
is need + inf without to
as in
i need change my attitude = i must change it
, needn't i?
