Talking things over with someone, listening to their problems, helping to find solutions and supporting them through the bad times is what counseling is all about. Families and frinds often take on the counseling roles for each other.
To begin with, could I use "family" to replace "families" in the above? If not, why not?
Second, is it equal to say "assume/act as/serve as counseling roles for each other" instead of "take on ...?" Thanks.
