Thank you a lot ,so here the difference between" and" and " or" is very small. However , a grammar book cites these two sentences: 1 he is not rich and handsome; 2 he is not rich or handsome. it says 1 means he is rich but he is not handsome while 2 means he is neither rich or handsome. The "and" and "or " are quite differenct in this structure , right ? Thank you again.
