LA you were quite right to take the kids out with you in the evening. I never put mine to bed early either (not that he'd have stayed in bed if I had). The concept of children's bedtimes is typically British, on the continent kids are up late eating with the rest of the family, running around laughing, screaming, joining in with everything. The Spanish, Portugese etc think we are cold in our attitude towards children just from observing that trait in the British.
Well I'm sure we are all agreed that it is a great pity the McCanns and their friends did not adopt the continental approach to dining out with young children - I expect they do now! From what I've heard loads of people with young children have completely changed their practices since little Madeline's abduction.
However we can't change the past which, in this instance, is a great shame - but there is no need to add to the tragedy by being hateful towards people who, with hindsight, acted unwisely with no ill intent, the consequence of which was and having someone so precious snatched away from them.
