Not boastful, but can't mention to mums in RL (did once and said sounded 'smug') but although they were a handful at times when toddlers, now as older children they (two boys) seemed to have turned into saints.
They always say please and thank you, ask to leave the table and hug me before they go out, ask me how I am and how my day has been, etc. It is just like living with adults really. But they are 9 and 13.
Is it simply that they are getting older / developing empathy? I can't remember ever telling them to do these things. Is it their schools (seem to have good discipline) or peer group?
Honestly, not trying to boast but wondering where does it come from?
