From my own childhood and from working with kids, you could get answers like
'Apart from being punched in the side of the head repeatedly because I looked at her a bit funny, not really'
'Dad got pissed, smashed the house up and then told us he was going to kill himself'
'I was looking after my little sister because Mum had to work. It was dark and the lights didn't work, so we were scared when there was somebody knocking'
'The boy that lives across the road got stabbed in the park'
'The lady next door gave us some sandwiches because we didn't have any food during the day'
'We went to the food bank and they said we couldn't have anything because the job centre didn't make a referral, they just gave the address'
'We drew some flowers on the path with chalk and the woman across the road said we'd be arrested'
'Nothing. Dad went to the shop and left us alone, then he went to sleep when he came back'.
'Mum got angry with us because nobody let the dog out when she was at work and Dad hit her'.
'I watched TV. Mum doesn't like me annoying her and after she picked up the metre stick and said if I got up one more time she'd wallop me with it, I stayed still'.
'We did the shopping and I helped carry things home'.
or, just the usual, not saying anything to let on just how awful the week has been, answer;
'Nothing'.
And then of course, the person asking then says 'Oh, you must have done something, mustn't you? All that playing, you're so lucky'.
Small talk can be intensely threatening for neglected, abused and vulnerable children.
