Grammar

can and could

0Hi,02br
02br
00I have difficulty in using the modals 'can' and 'could' mainly due to the fact that I feel they can be used in replacement of each other in some situations, exept for the fact that one is more polite than the other.02br
02br
00Are the sitations fit the above category of being easily replaceable with one another?02br
02br
01i00Please write 10 things you can/could do to be a better person.02i02br

0IMHO in your first three examples, the use of "can" seems to imply the possibility that any suggestions might be implemented, while "could" simply makes it sound like an exercise.02br

00In the last one, "could" is polite, although it's recently been argued in a post that technically speaking, we may be asking if the second person is able.0-
