I recently heard of an incident in a bungalow colony where a mother left her four year old to watch her two year old while she went in to take a nap. She was woken up 30 minutes later by a friend who found her two year old in the street.
The mother was appalled that someone obviously left the gate opened so that her two year old was able to walk out.
Please, in the country (or where ever), always make sure that the gates are closed and secured when going in and out. (And don’t leave your kids unless they are under the supervision of an adult or a competent teen.)
