Correcting my children

I love that my (teenage) children talk and share with me so much of their interactions with friends and peers from their extra-curricular activities. I feel like I correct them a lot when they share things they did or said (i.e. to teach them social skills or see how they could have been hurtful to someone, etc.), or if I feel they are being unkind/critical of someone. I want my children to continue to WANT to share and talk with me, but I don't want them to be discouraged and stop sharing because I am correcting them. How do you find this balance? I am pretty much their sole parent/teacher, and because we homeschool we are together a lot, so I feel the weight to teach and correct them in every area. I want to continue to fulfill my role, without it feeling "heavy" on my children.
