DH was walking home with DD7 and DS6. About 5 mins from home DS asks to go down this tiny cut through instead of path. DH says he'll meet them at an agreed location and he stays on path. But the cut through goes somewhere else and they end up in different places.
Turns out, that when they couldn't find him, the DCs decide to walk home, which involved walking along 3 streets and crossing one busy road at a zebra crossing. Apparently they ran into a woman we vaguely know who helped then cross the road.
DH instead of waiting at agreed place (Which they had to pass on their way back), went back to where they'd all started and missed then completely.
When DCs got home, I gave then a lecture about going anywhere on their own and talking to strangers. They both got really upset, especially DS.
But I really don't know what to say to DH. Everything's awkward as I don't want to raise it as it will cause an argument. I keep thinking about what could have happened to them.
