What are the things your parents did that you will never do to your kids or future kids?

One thing that I didn’t particularly enjoyed that my mother when I was a kid was when my mother “badmouth” me to her friends or relatives (in front of me). For instance, when others praised me for being well mannered, she will go: “no la! You should see her when she’s at home.. *spills embarrassing details of a certain tantrum episode*”. I’m sure the intention was not to put me down and more likely to be humble (perhaps?) in front of others or it’s just something that Asian parents do. But as a kid, I always hoped that there is a hole for me to disappear into. "What happens at home should stay at home." was my thought then. Haha. Well, I can’t guarantee that I won’t be doing that in future (since I supposed it’s quite ingrained in me now), but it sure left a deep impression.
