Limerick day trip

I went to Limerick today with the three Germans, Carolin, Stephanie, and Stephan. We caught a bus there at 10:30 this morning, arriving just before lunch. We immediately headed across town to St. Mary's Cathedral (built in 1168), which ended up being closed to the general public on Sundays. Oops. But after that we headed to King John's Castle, this amazing castle/ museum on the Shannon River. It was really gorgeous, and we had great weather, making the exploration that much more pleasant. They had even opened the archaeological dig site underneath the castle. Archaeologists excavated the area under the east (?) wall back in the 90s, uncovering old houses and such. It was incredibly exciting,at least to me. The excitement was soon overtaken by hunger. Our stomachs were eating themselves by the time we went through the castle, so we headed back towards the center of town. Just as we approached the bridge over the river, we noticed a pub that had outdoor seating. Since it was such a nice day, we thought we would like to sit outside. Turns out, they had an incredible lunch special, piles of Irish food for 5 euro. We were very happy eaters. We moseyed around town some more, watching street performers and looking at churches and art museums, and we made our way back to Galway around 6. I really liked Limerick. The town itself has a different feel than Galway, but it was really... easy. Almost comfortable. Is it possible that I'm getting used to life in Ireland?
