Made A Bad Impression On Friend's Dad.?

So This Ladie's Daughter Hit My Friend's Little Sister In The Stomach And She Started Crying (Shes 4 btw) And So My Friend's Dad Came Up And Confronted The Lady. My Parents Were Watching So When My Parents Asked What Happened, Her Dad Started To Speak When I Told My Other Friend Out Loud Who Was With Me During The Incident 'DON'T GET INVOLVED BY THE WAY!' And My Friend's Dad Got Quiet. I Didn't Know It Would Be Rude To Say That Cuz I Usually Have Freedom To Say Anything (That Doesn't Mean I Cuss Or Anything Cuz I Don't And Hopefully Never Will) And My Parents And Big Sister Got Mad And Now I Feel Really Bad Even Though Ik That I Didn't Know It Would Be Rude (I Said That To my Parents But They Don't Care). I Can't Apologize Because He Rarely Comes Out And I Don't Go To Her House. I Usually Try To Be Polite To Adults And Not Speak Casually With Them And Say Rude Stuff But I Didn't Know And I Don't Want Her Mom To Dislike Me Because She Likes Me (Not In The Way Like I'm Her Family Or Anything) And Her Dad Probably Thinks I'm Rude Now.
