I am well prepared to be called a stick in the mud for this one, but here goes.
At my mother and baby group this week the hostess offered everyone a beer, one girl had a gin. Most people were walking home, but one girl drove. I'm not sure why it seems weird to me. If we had all met for lunch and if I was not driving I would possibly have had a wine, but it just seems bad somehow to be in someones house drinking alcohol at 3 in the afternoon whilst your children crawl about on the floor.
While I was pg I went on a postgrad marketing course and one of the speakers was from New Zealand's road safety organisation. She was saying that they had done an ad about this very thing, but pulled it before it ever made it onto TV because people would say it was unrealistic - even though they had probably seen it happen.
So, how common is it? I couldn't bring myself to offer people who were going to drive a child home a drink, if anything happened I would feel too guilty.
