I've taken Doug up on his very kind offer and had a little chat by pm in which he has been very helpful (don't know if you got my second message Doug? Pm's not showing as sent). If me, my husband and 2 kids end up buried in the outback you can say 'I told you so' but be warned Doug if you're thinking of robbing us you chose the wrong family as you'll be sorely disappointed! Haha. It's funny you know how our minds can be conditioned and how society has evolved to be super suspicious but I'm willing to take the risk as I think this is a genuine offer from someone happy to help others and I for one appreciate it. To be honest we would be taking a similar risk getting into a taxi I feel and we wouldn't have the opportunity to get to know the taxi driver beforehand.
