I know this is a thread about a thread but it was really irritating me.
"I don't like precocious children", "I don't want to engage with somebody's precocious child". Being precocious isn't in itself a bad thing! It just means unusually talented for their age.
Replace the word with 'cocky' and I'd understand, but written like that it makes no more sense than saying "I don't like shy children". Well, it makes sense, but it isn't what the many, many posters meant.
Rant over and I feel much better!).
