My wife and I agreed before we had kids that one of us would be dry when doing childcare and if out or both drinking e.g. mess dinners, we would make arrangements with people we trusted. Mostly family, but sometimes parents friends for sleepovers.
I am still not sure what happened in the McCann case, but I am equally sure our children would not be in the situation the McCann children were.
Im sure you are telling the truth, Im merely remarking that its a stange coincindence that there were two people in the space of a few post, generally most people get slaughtered at mess functions.
