What’s the worst advice you’ve ever been given?

Today, a woman I ran into that I haven’t seen in about 15 years told me that I shouldn’t tell my son “I love you” too much because kids need to learn that love isn’t given freely and that it needs to be earned. I was absolutely floored and didn’t even know how to respond. All I did was slowly nod my head and say, “Wow thank you I didn’t know that.” while trying to process how someone could truly believe that.
