Just try to stop the HABIT of doing it. And then don't worry about it - from what i've read from your other posts (hello, btw!), YOUR conscience will definitely give you a nudge and let you know. You will just feel bad and feel the need to say something, and it will be about something specific, and you will know what to say to "make up" for it. Or the other person will let you know they were hurt by something you said or did, and so then you also should apologize. Within boundaries.
