Visiting at a friend's house (not local) our 2 DDs, both age 3 playing - hers is slightly younger than mine.
Her DD and mine are doing a puzzle together and mine can't do it as quickly as hers can.
Her DD says something to my DD along the lines of "I can't believe you can't do this I've been doing it since I was two".
My friend replied "darling, don't be smug."
Was this a dig that my DD is developmentally behind or something? I ask genuinely as it's not a term that's used here where I live and I've just read another thread about 'smug' meaning superior.
AIBU to now be thinking her telling my DD off for being 'smug' was an implication that my DD was behind?
