We quickly learned in Dublin you are either a Southsider or a Northsider, meaning you either live North or South of the River Liffey. We are Southsiders. We haven't learned completely what all the stereotypes are yet, but some say the North side is a little rougher. I took a picture of this Bulmer's cider advertisement playing up the divide.
Below is a sunset view of the Liffey, or the dividing point for the city of Dublin.
