8. Be aware of unhelpful relationship patterns. "For example, if a friend has been ringing you everyday [sic] to tell you how miserable they are, won't try things that are likely to help their mood, and never asks about your day, you might need to figure out how you can set some limits and expectations without withdrawing your support. Doing this in the right way is likely to benefit both of you."
If I want to quote a paragraph or sentence from others' writings for the sake of learning. But it contains a grammatical error, should I use [sic]?
P.S.: Please note that I just want to work it out not to wrong others.
