When I was younger I used to have to keep telling myself: The past is the past and there is nothing that can be done about it now, so stop playing the same events through your mind over and over again because it’s just suffering for no purpose.

You may have made them feel uncomfortable at the time but maybe you also opened their minds up to new ideas and possibilities that they wouldn’t have thought about had you not said that. Sometimes people can take years of build up before they try to understand themselves on a deeper level and it takes comments like the one you made to add up over time until their threshold is reached and it causes action. They probably won’t forget what you said and it probably isn’t a bad thing.
