Being one of twelve children I can honestly say that the culture, as such, doesn't differ that greatly. The difference lies in expectations and behaviours. Responsilities are different, particularly as an older member and there is very little alone space or time. On the other hand that is a great point, particularly when you want to play a game of cricket or touch football. We never had a lot of toys but what we did have we shared and created some great games with our limited resources. One major difference I have noticed is being able to listen to a number of conversations at once and know exactly what's going on.
We were raised to respect each other and those around us. At the same time we were taught to ask questions and not accept an argument just because it was given by a person in authority. You can imagine the discussions that went on around our dinner tables. To this day I would never change my family circumstanes, because this made me who I am today.
